Module nester 

Converts a flat collection of matches into a nested form suitable for replacement. When there are multiple matches for a node, or that overlap, priority is given to the earlier rule. Nested matches are only permitted if the inner match is contained entirely within a placeholder of an outer match.

For example, if our search pattern is foo(foo($a)) and the code had foo(foo(foo(foo(42)))), then we’ll get 3 matches, however only the outermost and innermost matches can be accepted. The middle match would take the second foo from the outer match.
