Range is both a sequence and an interval, and this is deeply wrong.

Consider:

irb(main):008:0> r =3D 'a'..'aa'
=3D> "a".."aa"
irb(main):009:0> r.to_a
=3D> ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m",
"n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "
x", "y", "z", "aa"]
irb(main):010:0> r.include? 'c'
=3D> true
irb(main):011:0> r.cover? 'c'
=3D> false

It's false. I don't know about you, but this seems quite
counter-intuitive. #to_a and #include? treat range as a sequence,
#cover? as an interval. But it's just the beginning:

irb(main):012:0> r =3D 'b'..'aa'
=3D> "b".."aa"
irb(main):013:0> r.to_a
=3D> []
irb(main):014:0> r.cover? 'c'
=3D> false
irb(main):015:0> r.include? 'c'
=3D> false

Explain these three to me, would you. I think this was some time ago
reported to Ruby's bug tracker, the conclusion was that Range has a
"feature" that if start compares as bigger than end, it won't bother
generating the sequence - this obviously fails for many non-numeric
ranges, as the one above. I don't think anything was done about it,
though.
