I agree, actually I suggest if you use:
fun f: int * int -> int
it stays with numbers but if you use
fun f(x:int,y:int) : int = """ f ($x. $y) """;
it goes with names.
This would have to apply to type variables as well.

This is really hard to do because C++ grammar is not even context free.
One needs to know what is a type name. I don't see how to complle
"snippets" of C++.
The best we can do is use separate compilation (plugins).
