Thanks for your response! Even if it's just to say RTFC. :) I have
been digging into the source regularly. It's a bit too complicated
for me to understand right now, and I find often the way core matchers
are written is appropriate for code that is going to be distributed
with RSpec, but not for code that is going to be maintained outside of
But you're right, once I understand the RSpec internals, It'll be easy
to write matchers with a different architecture. It's just slow going
