Why is it a mistake? That seems a very sane thing, although somewhat quirky. 
Since ElementType is a Range primitive, and apparently iterating through a 
string as a range will produce each semantically meaningful Unicode 
character rather than each UTF-8 or UTF-16 codepoint, it does make sense to 
do this.

Actually I found the explanation at 
http://dlang.org/phobos/std_range_primitives.html#ElementType.
