Is there an inverse 'member?' method in ruby?

Question

I often find myself checking if some value belongs to some set. As I understand, people normally use Enumerable#member? for this.

end_index = [\         


        

Answer 1

Unless you are dealing with elements that have special meaning for === like modules, regexes, etc., you can do pretty much well with case.

end_index = case word[-1]; when '.', ','; -3 else -2 end
