Howdy!

I'm using Test::More in my module test scripts. In testing the ways one can create a copy of an object, I use the eq_hash utility function to compare two objects (since they are hash based objects). This works fine except for one niggling detail.

A couple of the attributes are computed on the fly as needed and cached in the object. Other operations invalidate that cache as appropriate. One of the copy methods is a full copy, but the other only copies the data that must be saved, ignoring the cached data.

I'm thinking that it would be useful to have a version of eq_hash that takes a list of hash keys to ignore in the comparison.

I envision something like:

ok eq_hash($hashref1, $hashref2, [qw/key1 key2/]), 'partial hash compa
+rison';

I'm open to suggestions, etc.

yours,
Michael
