 .PP
-A Tcl expression consists of a combination of operands, operators,
-parentheses and commas.
-White space may be used between the operands and operators and
-parentheses (or commas); it is ignored by the expression's instructions.
-Where possible, operands are interpreted as integer values.
-Integer values may be specified in decimal (the normal case), in binary
-(if the first two characters of the operand are \fB0b\fR), in octal
-(if the first two characters of the operand are \fB0o\fR), or in hexadecimal
-(if the first two characters of the operand are \fB0x\fR).  For
-compatibility with older Tcl releases, an octal integer value is also
-indicated simply when the first character of the operand is \fB0\fR,
-whether or not the second character is also \fBo\fR.
-If an operand does not have one of the integer formats given
-above, then it is treated as a floating-point number if that is
-possible.  Floating-point numbers may be specified in any of several
-common formats making use of the decimal digits, the decimal point \fB.\fR,
-the characters \fBe\fR or \fBE\fR indicating scientific notation, and
-the sign characters \fB+\fR or \fB\-\fR.  For example, all of the
-following are valid floating-point numbers:  2.1, 3., 6e4, 7.91e+16.
-Also recognized as floating point values are the strings \fBInf\fR
-and \fBNaN\fR making use of any case for each character.
-If no numeric interpretation is possible (note that all literal
-operands that are not numeric or boolean must be quoted with either
-braces or with double quotes), then an operand is left as a string
-(and only a limited set of operators may be applied to it).
+An expression consists of a combination of operands, operators, parentheses and

-.SS "STRING OPERATIONS"
-.PP
-String values may be used as operands of the comparison operators,
-although the expression evaluator tries to do comparisons as integer
-or floating-point when it can,
-i.e., when all arguments to the operator allow numeric interpretations,
-except in the case of the \fBeq\fR and \fBne\fR operators.
-If one of the operands of a comparison is a string and the other
-has a numeric value, a canonical string representation of the numeric
-operand value is generated to compare with the string operand.
-Canonical string representation for integer values is a decimal string
-format.  Canonical string representation for floating-point values
-is that produced by the \fB%g\fR format specifier of Tcl's
-\fBformat\fR command.  For example, the commands
-.PP
-.CS
-\fBexpr\fR {"0x03" > "2"}
-\fBexpr\fR {"0y" > "0x12"}
-.CE
-.PP
-both return 1.  The first comparison is done using integer
-comparison, and the second is done using string comparison.
-Because of Tcl's tendency to treat values as numbers whenever
-possible, it is not generally a good idea to use operators like \fB==\fR
-when you really want string comparison and the values of the
-operands could be arbitrary;  it is better in these cases to use
-the \fBeq\fR or \fBne\fR operators, or the \fBstring\fR command instead.
 .SH "PERFORMANCE CONSIDERATIONS"
 .PP
-Enclose expressions in braces for the best speed and the smallest
-storage requirements.
-This allows the Tcl bytecode compiler to generate the best code.
-.PP
-As mentioned above, expressions are substituted twice:
-once by the Tcl parser and once by the \fBexpr\fR command.
-For example, the commands
+Where an expression contains syntax that Tcl would otherwise perform
+substitutions on, enclosing an expression in braces or otherwise quoting it
+so that it's a static value allows the Tcl compiler to generate bytecode for
+the expression, resulting in better speed and smaller storage requirements.
+This also avoids issues that can arise if Tcl is allowed to perform
+substitution on the value before \fBexpr\fR is called.
 .PP
+In the following example, the value of the expression is 11 because the Tcl parser first
+substitutes \fB$b\fR and \fBexpr\fR then substitutes \fB$a\fR.  Enclosing the
+expression in braces would result in a syntax error.
 .CS
 set a 3
 set b {$a + 2}
 \fBexpr\fR $b*4
 .CE
 .PP
-return 11, not a multiple of 4.
-This is because the Tcl parser will first substitute \fB$a + 2\fR for
-the variable \fBb\fR,
-then the \fBexpr\fR command will evaluate the expression \fB$a + 2*4\fR.
-.PP
-Most expressions do not require a second round of substitutions.
-Either they are enclosed in braces or, if not,
-their variable and command substitutions yield numbers or strings
-that do not themselves require substitutions.
-However, because a few unbraced expressions
-need two rounds of substitutions,
-the bytecode compiler must emit
-additional instructions to handle this situation.
-The most expensive code is required for
-unbraced expressions that contain command substitutions.
-These expressions must be implemented by generating new code
-each time the expression is executed.
-When the expression is unbraced to allow the substitution of a function or
-operator, consider using the commands documented in the \fBmathfunc\fR(n) or
-\fBmathop\fR(n) manual pages directly instead.
+
+When an expression is generated at runtime, like the one above is, the bytcode
+compiler must ensure that new code is generated each time the expression
+is evaluated.  This is the most costly kind of expression from a performance
+perspective.  In such cases, consider directly using the commands described in
+the \fBmathfunc\fR(n) or \fBmathop\fR(n) documentation instead of \fBexpr\fR.
+
+Most expressions are not formed at runtime, but are literal strings or contain
+substitutions that don't introduce other substitutions.  To allow the bytecode
+compiler to work with an expression as a string literal at compilation time,
+ensure that it contains no substitutions or that it is enclosed in braces or
+otherwise quoted to prevent Tcl from performing substitutions, allowing
+\fBexpr\fR to perform them instead.
