I see. Still, the solution seems easy enough. Just treat the overloaded types 
as part of the function name:

  foo(int n)
  foo(float x)
  foo(string s)


  foo_int n
  foo_float x
  foo_string s

When you come across:


you look up the statically inferred type of "a" and just bail if it fails to 
match any of the overloads.

Generics are left alone:

  foo<T>(T x)


  foo (x : 'T)

Would that work?
