D - [BUG] nested overload fails

Shouldn't this nested overloaded function compile and work?

void main ()
{
void Test ( int i ) { printf("i=%d\n",i); }
void Test ( int i, int j ) { printf("i=%d, j=%d\n"); }
// over.d(4): declaration main.Test is already defined
Test(1);
Test(2,3);
}

Apparently you can't have nested overloads.  Frankly I don't see much 
use for this here (generally) anyhow as your not going to get much reuse 
of overloads in nested scope and overloads like this are about reuse.

Just trying to get the same convenience I would have had with #defines in C/C++.
No big thing, but I don't see why it should work at global scope, but not when
nested in a function.  In C, I use local #defines to make repetitive code
clearer to read, it's useful.

It would be nice for consistency.
