Apparently, ElementType!string evaluates to dchar. I would have expected char. Why is that?
I think is because they are iterated by ranges as dchar, that's equivalent to iterating the unicode symbol.
If they were iterated by char, you would get during the iteration the singles pieces of the utf8 encoding, and usually that is not what an user is expecting.
Note on the other side that static assert( is(typeof(" "[0]) == immutable(char)) ), so you can iterate the string by chars using the index.
