[Python-Dev] PEP 246, redux (original) (raw)

I had been promising to rewrite PEP 246 to incorporate the last several years' worth of discussions &c about it, and Guido's recent "stop the flames" artima blog post finally pushed me to complete the work. Feedback is of course welcome, so I thought I had better repost it here, rather than relying on would-be commenters to get it from CVS...

Thanks for doing this, Alex! I yet have to read the whole thing [will attempt do so later today] but the few snippets I caught make me feel this is a big step forward.

I'm wondering if someone could do a similar thing for PEP 245, interfaces syntax? Alex hinted that it's a couple of rounds behind the developments in Zope and Twisted. I'm personally not keen on needing two new keywords (interface and implements) so I hope that whoever does the rewrite could add a section on the advantages and disadvantages of the 'implements' keyword (my simplistic alternative proposal is to simply include interfaces in the list of bases in the class statement; the metaclass can then sort it out).
