Some time ago, Gareth McCaughan suggested a syntax for staticmethods.
You'd write
class C(object):
def static(arg) [staticmethod]:
return 1 + arg
C.static(2)
=> 3
The way this works is that the above becomes syntactic sugar for
roughly:
class C(object):
def $temp(arg):
return 1 + arg
static = staticmethod($temp)
Anyway, I thought this was a reasonably pythonic idea, so I
implemented it, and thought I'd mention it here. Patch at:
http://starship.python.net/crew/mwh/hacks/meth-syntax-sugar.diff
Some other things that become possible:
>>> class D(object):
... def x(self) [property]:
... return "42"
...
hello!
>>> D().x
'42'
(the hello! is a debugging printf I haven't taken out yet...)
>>> def published(func):
... func.publish = 1
... return func
...
>>> def m() [published]:
... print "hiya!"
...
hello!
>>> m.publish
1
>>> def hairy_constant() [apply]:
... return math.cos(1 + math.log(34))
...
hello!
>>> hairy_constant
-0.18495734252481616
>>> def memoize(func):
... cache = {}
... def f(*args):
... try:
... return cache[args]
... except:
... return cache.setdefault(args, func(*args))
... return f
...
>>> def fib(a) [memoize]:
... if a < 2: return 1
... return fib(a-1) + fib(a-2)
...
hello!
>>> fib(40)

I'm not sure all of these are Good Things (esp. the [apply] one...).
OTOH, I think the idea is worth discussion (or squashing by Guido :).
Cheers,
M.
