Is there any reason why arithmetic operation on shorts and bytes return int?

Agreed.

How about this.

1. Let "char" and "short" behave the C/C++ way. These can return integers.
This will make C/C++ code work in D.
2. Make D "byte" operations return bytes. And create another type (named
say dbyte or shortint) and make operations on the new type return
shortints. This will make these types more usable in D code. Well we end up
adding another keyword, but we shall get workable and safe 8-bit and 16-bit
integrals.
