Hi --

a = [1,2,3,4]
result = case
when a.include?(1): 'this is what i want'
when a.include?(11): 'not result'
when a.include?(15): 'no good'
end

ahhhhhhhhhhhhhhhh
perfect.

I'm curious about the fall-through case. If the array does not
include 1, 11, or 15, then result will be nil, which I assume is
equivalent to a "no good" result. That makes me wonder whether a
simple include? would work equally well. Or is there more to the
various error conditions?
