1. Look how it is mangled on the C++ side. (Use "grep" on the 
object file.)

2. Use:

   pragma(mangle, "the mangled name")

This doesn't work for templates. If it did I wouldn't have an 
issue since libclang tells me what the mangling is.

What is the deal-breaker with templates? For simple functions 
libclang + pragma seems the best option right now.

template fun()
{
    pragma(mangle, "_ZN2ns3funEv")
    extern(C++)
    void fun() {}
}

mixin fun;
