kikito: It’s a feature of Ruby 1.9 Array#flatten.

1.8.6 delivers ArgumentError. 1.8.7 appears to have backported it.

Jeremy: when you hoisted Ola’s suggestion into your update, you used [] when you meant ().

Hi guys,

How is this supposed to work? I don’t see Array.flatten accepting any arguments on the ruby apy.

If you care about subarrays, why don’t you just give flatten an argument?
Hash[*self.flatten(1)] will give you what you want.
