Hello,
I'm not a python-dev regular, so sorry if this is a FAQ. What's the status of defining a syntax for function attributes (PEP 232)? I'm using __doc__ to carry metadata about methods right now, but would very much like to use function attributes. However, without a specialized syntax, I'm stuck doing things like
VeryLongMethodName.MetadataName = "foo"
which is fine if it's a one-off, but I'd like others to use the code, and this isn't exactly a friendly mechanism. The proposals in the PEP would be fine; I was thinking something like
def foo(a): """this is the docstring""" .this_is_a_function_attribute = 1
but that's just off the top of my head.
I'm happy to do some work writing a PEP if there's some consensus about what syntax would be preferable.
Cheers,

I don't think changes here are likely.

If PEP <the one I haven't written yet> gets accepted, you'll be able to do
def with_metadata(func): func.metadata = "yes"
def f(blah) [with_metadata]: ....
or even
def with_metadata(data): def inner(func): func.metadata = data return inner
def f(blah) [with_metadata("yes")]: ....
Would that suit you?
Cheers, M.
