FilledSmallSquare Verbatim[expr] represents expr in pattern matching, requiring that expr be matched exactly as it appears, with no substitutions for blanks or other transformations.

FilledSmallSquare Verbatim[x_] will match only the actual expression x_.

FilledSmallSquare Verbatim is useful in setting up rules for transforming other transformation rules.

FilledSmallSquare Verbatim[expr] does not maintain expr in an unevaluated form.

FilledSmallSquare See Section 2.3.12.
