I was just going to make a __traits that returns a tuple of 
string lf the types as seen by the parser (i.e. "size_t"). While 
size_t and ptrdiff_t are the most common case they are not 
special. e.g.
version = B;
version(B)
{
     struct b{}
     alias A = b*;
}
version(C)
{
     struct c{}
     alias A = c*;
}
void foo(A a){}
writeln(Parameters!foo);//prints b*
writeln(__traits(whatevericallit,foo);// prints A
