Verbatim
 Usage
• Verbatim[expr] represents expr in pattern matching, requiring that expr be matched exactly as it appears, with no substitutions for blanks or other transformations.
Notes
• Verbatim[x_] will match only the actual expression x_. • Verbatim is useful in setting up rules for transforming other transformation rules. • Verbatim[expr] does not maintain expr in an unevaluated form. • New in Version 3.
