I've been threatening to implement such a beast for some
time; as soon as I have a free minute I'm still hoping to
get to it. I agree that it could be an important feature
and good selling point for Ruby.
Yes, the Eiffel style keywords have already been used.
In the few trial versions I've put together, I used
"pre" and "post" as the keywords, in addition to
an "invariant" method and a simple "check".
I believe that DbC can be added purely as an add-on in Ruby,
that no interpreter changes will be necessary -- Matz
is busy enough as it is, I'd rather not burden him with
anything extra if I can help it :-)
Perhaps I can carve out some time this week to give it
another look...
