Having actual new types makes me a bit nervous in regards to how 
overloads will be handled, and how templates will be instantiated.

I don't know how things happen behind the scenes, but (as I 
remember), writing "portable" C++ code to handle all possible 
integral primitives was a real hell, as on some systems, 
"foo(int)/foo(long)" would collide, whereas on others, you *need* 
both declared.

Will this start happening in D too now...?
