Any range of dchar could have a representation (or you may want to call 
it something else) that returns a range of char (or ubyte). And I think 
they are more generic because they use a generic API (ie range), that is 
very powerful: the representation can provide length, slicing, etc... 
that is different that the dchar length or whatever. You don't want to 
duplicate all range methods by postfixing Unit...

You proposed Jonathan to call Walter in an earlier post. I believe there 
is a misunderstandment.
