Subject: | Test::MockObject does not support perl 5.005 |
Test::MockObject doesn't work on 5.005, making it hard to use for testing things like CPAN modules that need to work as compatibly as possible.
Looking at the code it looks like it should be able to, although I'm not sure what the implications are for UNIVERSAL::can and UNIVERSAL::isa, which both also make heavy use of 5.006-minimum features.
