So... do we agree on
ascii: int - not found => -1

I'm not a fan of the ASCII version returning -1, but I don't really have a
better suggestion. I suppose that you could throw instead, but I don't know if
that's a good idea or not. It _would_ be more consistent with our other
conversion functions however.

I find low-level stuff that throws to be overly awkward to deal with
(not to mention performance problems).
Hm... I've found an brilliant primitive Expected!T that could be of
great help in error code vs exceptions problem. See the recent Andrei's
talk that went live not long ago:

Time to put the analogous stuff into Phobos?
