Diez,
notfound= object()
@enriched_decorator("bar")
def some_decorator(f, *args, **kwargs):
bar = kwargs.pop("bar",notfound)
return f(*args, **kwargs)
Then you would declare your function:
@some_decorator
def funA( x, y, z ):
do( x, y )
make( z )
And be able to call it:
funA( 0, 1, 2, bar= 'what' )
so some_decorator consumes 'bar' and preserves x, y, and z. It's
working fine. What did you want to ask about?
