Look for metaclasses or metaobject protocol.
Is there an example or two which demonstrates ruby can do things via metaprogramming / metaclasses / metaobject protocol that python cannot ? Something more than syntactic or stylistic differences. It wouldn't be normally fair for me to ask for that and I should go hunt it down myself, but given the earlier assertions made in this thread, i believe it is reasonable in this case. _______________________________________________ BangPypers mailing list BangPypers@python.org https://mail.python.org/mailman/listinfo/bangpypers
