Not that it matters, since it's already there, but no, I wasn't.  In
fact, the presence of partial is a big reason not to need prepartial
-- most existing use cases are already covered by using partial. As
Arnaud pointed out, if you restrict decorator_withargs to keyword
arguments, you don't even need prepartial, you can just use partial
itself.  Thus, I don't see prepartial as really covering many new use
cases.  If you'd like to convince me otherwise, you're going to need
to post some use cases from real code.
