Of course that should have been something more like:

> template tr(A...) { extern A tr; }
> template getOverload(alias func, A...) {
>     typeof(foo(tr!A)) function(A) getOverload = &func;
> }

and I should actually test the code before posting, even when the compiler
tries to make things difficult (Error: functions cannot return a tuple). ;)
While this version works now, it's still prevents getting the correct 
mangled function name - the getOverloads loop approach gets that right.
