That reads better as obj.within?(range) than as range.within?(obj). I
like #contain? personally, though in programming terms a "container" is
more a set than a range. Actually, I'm all for #include? to mean
bounding inclusion, and something a lot more expensive-sounding than
member? for #to_a set inclusion. Something like
"aaa"..."zzz".generates?("bbb") would at least indicate that it was
doing an O(n) stepthrough of the range.
