Bug 11340 – ElementType and ElementEncodingType return oddly qualified element types

----- import std.range; void main() { pragma(msg, ElementType!(string)); // dchar pragma(msg, ElementType!(wstring)); // dchar pragma(msg, ElementType!(dstring)); // immutable(dchar) pragma(msg, ElementEncodingType!(string)); // immutable(char) pragma(msg, ElementEncodingType!(wstring)); // immutable(wchar) pragma(msg, ElementEncodingType!(dstring)); // immutable(dchar) } ----- As far as I know these should all be const(T). Am I wrong?

As commented here: https://github.com/D-Programming-Language/phobos/pull/1660#discussion_r7189412 > dstring is a non-narrows string. Because of this, calling front gives you an > lvalue of the actual elements, as opposed to narrows strings, which give you > decoded dchar: They're mutable, but rvalues.
