That's pretty cool. :) (You meant reverse()).
Interesting, because there could be no other way anyway because
reverse() is in-place. Iterating by dchar without damaging the other end
must have been challenging because the first half of the string may have
been all multi-bype UTF-8 code units and all of the rest of single-bytes.
The algorithm must be building a local string.

It does not have to build a local string, see
