I've encountered several times, when dealing with adaptation of function
signatures, the need for explicitly resolving complex argument sets into
a simple variable mapping. Explanations.
Consider that function:
def foo(a1, a2, *args, **kwargs):
pass
calling foo(1, a2=2, a3=3)
will map these arguments to local variables like these:
{
'a1': 1,
'a2': 2,
'args': tuple(),
'kwarg's: {'a3': 3}
}
That's a quite complex resolution mechanism, which must handle
positional and keyword arguments, and deal with both collision and
missing argument cases.
Is that routine exposed to python, somewhere ? Does anybody know a
working implementation here or there ?

Too sweeeeeeeeeet \o/
Thanks a lot,
