Actually, I think I had envisioned the BIF not being invoked, but  
rather the local function.

In any case, at least there's a warning -- and if it's a warning,  
then no matter which way you resolve it, there's a chance the  
resolution didn't read the programmer's mind properly :)  If you  
really want strict (maybe it could be a compiler option), then this  
would be an error.
