I agree completely on this topic. I just can''t express how big a
selling point this feature was to me. It has made writing unit tests
a *dream* I can override functions in modules like PAM so that they
can run in automated tests.

Hey, be fair! While there are two sentences and two question marks it is
really only one question and the phrasing merely indicates two points of
views - pragmatic or simply wrong! Being a rubyist myself, I don''t think it
is inherently wrong, I think it is pragmatic!

This is an interesting idea, can you provide some more details?
Do you mean that you''re stubbing some methods which might not work in your
testing environment/context?
