The situation is even
worse with narrow strings (assuming that put works with them -
I'm not sure
that it does at the moment) given that even if you knew their
length (which
you wouldn't if you were going by hasLength), you wouldn't know
whether a put
would succeed when the string was nearly empty, as the actual
number of
elements that the dchar would take up would depend on its value.
Furthermore--you probably know this because of the conversation
on GitHub but for anyone else reading--narrow strings are also
hard to work with because you can't put a dchar on them
currently. Kenji had a pull request (since closed) to help with
narrow strings issues:
https://github.com/D-Programming-Language/phobos/pull/1000
That and all the issues and unknowns you describe would need to
fixed for output ranges are going to be the approach.
I'm reminded of a forum post by monarch_dodra that talked about
some of the issues you brought up:
