Could you name some names here? Regardless of how this whole thread
goes, maybe people will agree that those uses were indeed ill-advised,
and we can get them fixed up.
Perhaps the problem is that fromString is very easy to understand and
write, but quasi-quoters sound like a whole new complicated thing to
learn about. If we could either demonstrate that they're not so bad
to write, or have a little library that makes them easier for
"stringlike" things, then maybe we could move the first instinct away
from "hack a quick fromString" to "hack a quick QQ".
