Description:
module to traverse Perl data structures
With Data::Walk, one can have a call back function being called for each node in a given structure. It works with hash references, array references and blessed references of arbitrary depth. . Data::Walk is similar to File::Find, but instead of directory hierarchies, it works with Perl data.
