I see the use of that, but according to Zen, "Explicit is better than
implicit."

Why not?:
def foo(**kwargs):
kwargs["additional"] = 5
return other(**kwargs)

So really it's just a short hand. But it's against the Zen! Explicit
not Implicit! I'm not convinced....then again, I didn't look at the
source code of the standard libraries.
