Ruby Hash with duplicate keys?

Question

Is it possible to create a hash in Ruby that allows duplicate keys?

I\'m working in Ruby 1.9.2.

Answer 1

This would kinda defeat the purpose of a hash, wouldn't it?

If you want a key to point to multiple elements, make it point to an array:

h = Hash.new { |h,k| h[k] = [] }
h[:foo] << :bar
h #=> {:foo=>[:bar]}
h[:foo] << :baz
h #=> {:foo=>[:bar, :baz]}
