Recursive map, apply a block to a data structure

Recursively evaluate a BLOCK over a list of data structures locally setting $_ to each element and return the list composed of the results of such evaluations. $_ can be used to modify the elements.

DataRmap currently traverses HASH, ARRAY, SCALAR and GLOB reference types and ignores others. Depending on which rmap_* wrapper is used, the BLOCK is called for only scalar values, arrays, hashes, references, all elements or a customizable combination.
