Why doesn’t 0 (Fixnum) support .each ?
1 does, so does 2, 20, 200, and so on.
Why not 0? Why doesn’t 0.each simply do something 0 times?
NYARGH!

Because Fixnum doesn’t have the method `each’.
1 does, so does 2, 20, 200, and so on.
All of them don’t.

1#each doesn’t exist either.
You’re probably thinking of #times, which is defined for 0, 1, 2, …

They don’t, because they’re single items, not lists, sets or something.

Because 0.times { } does that.
alternatively, Range#each works.
