Well, it is possible that it is actually checking that code since  
Devel::Cover hooks into perl at runtime to check code coverage,  
however it cannot report on it since it cannot match it to the actual  
source. This is a common issue with code generation modules like Moose.

Actually, I think Anders worked really hard to get Devel::Cover to  
work with MX::Method, although I don't know what the final outcome was.

No, there isn't anything but Devel::Cover as far as I know. However,  
to be completely honest, the code that Moose generates has already  
been tested pretty thoroughly in the Moose test suite and it's  
behavior verified. So you really shouldn't need to worry about having  
to re-test it yourself. Personally, when I test code-coverage on my  
Moose based modules, I tend to just look to make sure I have coverage  
on *my* methods and don't worry about the Moose generated stuff.
