Function overloading concern

[Sean Kelly]

I mulled this over a bit more, and I think the existing rules will work 
so long as template code is carefully designed with it in mind.  For 
example, where a template might rely on another overloaded template in 
C++, it might be prudent to parameterize it in D.  And with classes as 
reference types in D, there's a much smaller need for specialized swap 
functions.  My only remaining concern is traits templates in D, as they 
basically rely on cross-module overloading.  But perhaps this is 
something best sorted out by experimentation--DTL will likely have to 
deal with it sooner or later in any case ;-)
