my $is_different = compare($ref1, $ref2);
DESCRIPTIONCompares 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!
$bool = compare($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.
compare currently does not deal with blessed references. I need to look into how to deal with this.
