I wouldn't necessarily trust the output of .stringof; it's known to be buggy 
in a lot of cases.  See if you can get the compiler to spit out an error 
containing the type, i.e.

void blah(T)()
{
    SOME_INVALID_FUNCTION();
}

...

blah!(PCHAR)();

This should make the compiler spit out some kind of error with the name of 
the instantiated blah, type included.
