Convert Array to Hash

Probably nothing new in this but here is one way of converting an Array to a Hash:

   1  
   2  require "enumerator"
   3  
   4  class Array
   5    def to_h
   6      Hash[*enum_with_index.to_a.flatten]
   7    end
   8  end
   9  
  10  %w{a b c d}.to_h  # =>  {"a"=>0, "b"=>1, "c"=>2, "d"=>3}
