That's a great explenation of some of the hardest-to-understand
corners of RSpec. Thanks a lot for writing it! It's very pedagogic.
Regarding the stability of the API - I'm a little worried about having
extensions use private variables. I think it would be better to pass
the module to the method:
A second point is monkey patching. I'm not convinced it's the best way
to do things - it makes things tricky when you want to tweak things
more than once (see my mail from yesterday - I want to mix the
screenshot stuff with fixtures).
I haven't thought of an alternative way yet, but I think we need to be
able to register "extension" blocks somehow.
