PEP? context overloading: if wants(type): ...

I'm not qualified to formally champion a PEP, but I'd
like to raise the question here to see if it's of interest.
One feature that I find interesting about PERL is it's
"context sensitivity." (By contrast the inability to overload
a function on *return* type is a limitation of C++ that I find
irritating and unnecessary).
I'd propose, if I felt qualified to do so, to offer a "wants()"
or builtin that would allow a method to determine the desired
return type or "context" of an invocation.
So the use could look like:
elif wants(VoidType): # NoneType?
What am I missing about this? What would it hurt?
