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

       •   $bool = compare($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

       •   blessed references

           compare currently does not deal with blessed references. I need to look into how to
           deal with this.
