Why hasLength!string is false:

Would it make sense to introduce a hasOpaqueLength oslt. to fix this?
You mean std.array.join? The 2-argument overload has specialization for
strings
(https://github.com/D-Programming-Language/phobos/blob/master/std/array.d#L966).
static if (isForwardRange!RoR && hasLength!RoR
&& (hasLength!(ElementType!RoR) ||
isSomeString!(ElementType!RoR))
//
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
&& hasLength!R)
It doesn't exist for the 1-argument overload though.
