import core.sys.windows.winbase;
import std.string;

export extern(C) T foo(T)() {
     return 1234;
}

int main(string[] argv)
{
     int x = foo!int;

     auto handle = GetModuleHandleA(null);
     auto fooInt = cast(int function())GetProcAddress(handle, 
foo!int.mangleof.toStringz);
     writeln(fooInt());

     return 0;
}

Awesome.. this actually works.
