Re: [Python-Dev] syntax for funcion attributes

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 don't think changes here are likely.
...
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.
If PEP  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.
