Hi Anders
Thank you for your interesting message. I'm sure it's based on a real
need. You wrote:

I assume you're talking about defining functions. Here's something
that already works in Python.
>>> def fn(*, a, b, c, d, e): return locals()
>>> fn.__kwdefaults__ = dict(a=1, b=2, c=3, d=4, e=5)
>>> fn()
{'d': 4, 'b': 2, 'e': 5, 'c': 3, 'a': 1}
And to pick up something from the namespace
>>> eval('aaa', fn.__globals__)
'telltale'
Aside: This is short, simple and unsafe. Here's a safer way
>>> __name__
'__main__'
>>> import sys
>>> getattr(sys.modules[__name__], 'aaa')
'telltale'
>From this, it should be easy to construct exactly the dict() that you
want for the kwdefaults.
