Nor should it. If a class defines the concept of equality for itself, any external equality-testing framework should respect that. (btw - those interested should refer to FAQ How do I test the deep equality of two hash tables?)	[reply]

Sometimes it should, especially when testing the overloaded objects. It is the lack of any is_deeply test which is able to see through overloading that lead me to do something hokey and do cmp_eq( Data::Dump::Streamer::Dump($a), 'eq', Data::Dump::Streamer::Dump($b) ) tests instead. If an overloaded object wanted to pretend to be normal, it can use an utterly normal test and it'll get called as usual. Its the stuff like Test::More which should be able to have x-ray eyes to see through overloading.	[reply]

But I don't think that's a problem. You're doing an "out of band" test, you should have to jump through hoops. Whereas if, in the course of an application, I want to know, "are these two widgets equal?" I should depend on any overloaded equality ops to do the right thing, not to second-guess what the right thing should be.	[reply]

Maybe the appropriate action is to have a Test::More flag that specifies whether to use overloading or have xray vision. Maybe it should be $Test::More::XRAY_VISION? :-) In general, if you think something isn't in Perl, try it out, because it usually is. :-) "What is the sound of Perl? Is it not the sound of a wall that people have stopped banging their heads against?"	[reply]
