I can use UNIVERSAL::isa and UNIVERSAL::can in my code to warn people that things will break if they use them incorrectly and to try to route around the damage as much as possible.

I agree with you 100%, however, the problem is that UNIVERSAL::can actually dies, and not just warns in this particular case. The last error in the OPs post ...

Can't call method "can" on an undefined value at /usr/local/share/perl/5.8.4/UNIVERSAL/can.pm line 40.
is actually UNIVERSAL::can die-ing. This is is something too that (IMO) can be routed around fairly easily so I sent you a patch and test for this.
