perl module to compare perl data structures recursively


The Data::Compare module compares two perl data structures recursively, it natively handles several built-in data types - scalars, references to scalars, references to arrays, references to hashes, references to subroutines, compiled regular expressions, and globs. For objects, it tries to Do The Right Thing and compares the underlying data type.

However, this is not always what you want. This is especially true if you have complex objects which overload stringification and/or numification. So you can extend this module with your own plugins for special data structures, by using Data::Compare::Plugins (this is not an extra package, it is included here).
