I understand that, and while you're doing that I can begin 
implementing the PRs to deprecate `in` or change its definition 
to `scope const`, or something else.

Nothing I'm proposing will, in any way, interfere with what 
you're doing in Phobos.  I just want a decision about what we're 
going to do with `in`.  I'll do the leg work.
