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).
