NAME
Struct::Compare - Recursive diff for perl structures. SYNOPSIS
use Struct::Compare; my $is_different = compare($ref1, $ref2); DESCRIPTION
Compares two values of any type and structure and returns true if they are the same. It does a deep comparison of the structures, so a hash of a hash of a whatever will be compared correctly. This is especially useful for writing unit tests for your modules! PUBLIC FUNCTIONS
o $bool = compare($var1, $var2) Recursively compares $var1 to $var2, returning false if either structure is different than the other at any point. If both are undefined, it returns true as well, because that is considered equal. BUGS
/NEEDED ENHANCEMENTS o blessed references compare currently does not deal with blessed references. I need to look into how to deal with this. LICENSE
