Ugh.

I think this is a sign of why we did it the way we did with that odd
"typeof(*p)*" thing in the first place.

The thing is, in any normal C, the function name should just stand in
for the pointer to the function, so having to add a '&' to get the
function pointer is somehow odd..

So I think you should just expose your type to anybody who uses a pointer to it.
