Implementers of D function libraries will likely want to implement different routines for char's and wchars.  Sure, you could implement all of your string functions as wchar*'s, but that requires a pretty terrible conversion process.  It would be cool if there was some syntax where you could declare a single function in the code but it automatically expands to two versions of it - a char version and a wchar version.

Ofc, templates do this, but I'm looking for something that might work w/o having to implement templates.  Maybe a special type that could only be used as a function parameter or return type.

Brainstorms?

The D spec seems to frown on macros, but this is is a very good use for them.
