I'm usually resistant to change for change sake but I really like the
idea of mock_model or something like mock_armodel. I never knew that
RSpec had something like that, I use Shoulda myself. But I would
really really like to see this in future versions of Mocha.
Also, perhaps the work in the Shoulda gem on Github might give you an
idea on how you can incorporate this into Mocha and just use a require
or config.gem lib like 'mocha/rails', which is something Shoulda does
since you do not have to use Shoulda with rails but if you do you get
their ActiveRecord macros, etc.
