No need to apologize.  Tangents can be fun.

I don't dislike the answer - I was just curious about the change. But
now I'm wondering about David's earlier statement that under 1.9,
('!'..'~').to_a works 'correctly'. Does this mean that Range.each has
even more special cases for Strings?  That would be unfortunate.   It
seems cleaner if Range could use an alternate method (#advance ?)
which would be an alias for #succ in class Object, but would be
overridden by String and other classes where x.succ doesn't always
compare greater than x.
