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:

 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.
