An alias parameter to a template would actually be the ideal

I just pushed an update that should support this.
It can now resolve aliases and lambdas properly. This means
things like this will work correctly.
module pack.test;
int foo() { return 0;}
int foo(int i) { return i+1; }
void foo(double d) { }
foreach(overload; __traits(getOverloads, pack.test, "foo"))
writeln(__traits(codeof, overload);
Also, passing lambdas via template alias parameters works. So
something like this should work as well.
void foo(alias dg)() {
writeln(__traits(codeof, dg));
}
void main() {
foo!(x=>x+1)();
}
