I agree.

I'm absolutely happy with the way D handles foreach loops on strings and
char[].

However, disambiguation of foreach loops for char and wchar is a an issue that
should be addressed. I think the best solution would be to mave it the coding
standard to specify the char/dchar/wchar.

Issuing a warning whenever you iterate over a string or dstring without
explicitely declaring char/char/wchar would indeed be the way to do so. The
user is still free to ignore the warning, but accidental misuse would be
avoided and a consistently clear coding style would be encouraged.
