[Python-3000] yes to class decorators

yeah, i just wanted to bring it up again. however, i do have some
spare time at the moment, so i can write the pep myself.
but before someone writes a pep, it's better to discuss the issue
at hand.

currently, to my understanding, this is what we have:

("@" expression "\n")*
"class" name ["(" expression "):"]
    clause

we should find some more/better use-cases than what i came
up with, and show why class decorators are the right solution,
and compare with function decorators.

we should also note that it's possible to replace "__metaclass__"
by a @metaclass decorator. of course this requires more thinking.

i don't get your point. i DID read many posts about class
decorators, the most recent of which i've seen were at least half
a year old.  since we have Guido's blessing on the subject,
i wanted to get the wheels moving.

of course i couldn't read EVERYTHING that was said about
class decorators, so i added a couple of use-cases i found.
in fact, the reason why i posted yesterday was because i wrote a
singleton class, and wished i had @singleton instead of

class Foo(object):
    pass
Foo = Foo()

so if we put aside your Stalinistic behavior for the moment,
do YOU want to write the pep? please do.

i don't see why this thread bothers you so much, but you could
have prevented it by writing a pep months ago.
now isn't that motivating? :)
