RFC: Devel::Mockable and Devel::Mock::Generic::InterfaceTester

[CCing chromatic in case he's not on perl-qa; my apologies if you get
two copies]

I'm liberating some code that we use at work.  A first cut at CPAN-
ising it is here (yes, I know it has no tests yet):
  https://github.com/DrHyde/perl-Devel-Mockable

What do people think?  The aim is to:
  * make it easy to make your code's interfaces to other code
    mockable;
  * test that your code calls other code correctly, without
    all the overhead of actually calling that other code

I don't think it's really doing the same job as Test::MockObject.
That's more for mocking things that might feed data *into* your code,
whereas mine is aimed more at testing how you call those other things in
the first place.  Also I think that my code's interface is nicer :-)
