I was thinking we could tag the current master as 1.6.0 and call it a
release. I hate to leave people -- especially people who get their copy
of iterate from quicklisp -- stuck using a version of iterate that has
known bugs for which a fix has been committed.
I would bump the current version number to 1.6.0 to indicate that there
are new features but that we are backward-compatible.
Note that we now warn on the use of `count`, but I would argue that
emitting a warning isn't a true backwards incompatibility, and the new
state of `iterate` doesn't seem to warrant calling it 2.0
Thoughts? Anyone even read this mailing list?
