For the following code:

#import std.stream;

#void main()
#{
#    std.stream.stdout.write("There is no spoon");
#}

I get this error: StreamWriteTest.d(5): function std.stream.Stream.write
overloads void(char[]s) and void(wchar[]s) both match argument list for write

Is there a clean way to fix this?  Do I have to cast this string?

Yes.

Possible solutions (previously suggested)

0- Do nothing, cast is sufficient.

1- Allowing a prefix to the string i.e.
> #    std.stream.stdout.write(w"There is no spoon");
(denoting that it's a wchar)

2- Where collisions occur assume a literal string is char[].

3- Decide the type based on the contents.

I have no problem with (0), (1) is simply another way to express the same thing which is the programmer stating "this literal is an x[]".

(2) might have hidden bug consequences in the (unlikely?) event there are 2 functions of the same name taking different char types, doing different tasks.

(3) is like (2) except it's additionally optimisation, after all UTF-8, 16, and 32 can all represent all the information, they just do it with differing byte usage.
