Recently there has been another heated debate on Github about whether
ranges should auto-decode at all:
https://github.com/D-Programming-Language/phobos/pull/2423
Jonathan is about to write up a DIP for phasing out auto-decoding. Given
that, I think we need to decide which direction to take, lest we waste
energy on something that will be going away soon.
