Shortcut to make case/switch return a value

Question

I\'m pretty sure I saw someone do a shortcut technique like the code below (which doesn\'t work)

return case guess
  when guess > @answer then :high
  whe         


        

Answer 1

Picking up on @mu's first comment on the question (an approach that looks fine to me), you could of course also write that as:

return case (guess <=> @answer)
       when -1 then :low
       when  0 then :correct
       when  1 then :high
       end

or

       ...
       else
         :high
       end
