Handy way of mapping values in Ruby

There is something I like about Ruby that you can do in some languages but not most languages.

Here is an example:

grade = case points
  when 94..100 then :A
  when 83..93 then :B
  when 75..82 then :C
  when 65..74 then :D
  else :F
end

You can do something very similar in LISP using the COND function and in MUMPS using the $SELECT function. Most languages do not have something this convenient.
