Subject: Help using ruby enumerator idioms

Hi,

In Ruby, when I see something like:

h = []

x.each do

...

end

h

Usually means that I can refactor it to use map, inject, select, or
reject.

However, I am unsure how to do this for the code below:



         h = Hash.new {|hash, key| hash[key] = {}}

   some_hash_of_hashes.each do |hash_key, sub_hash|
     sub_hash.each {|key, value|   h[key][hash_key] = value }
   end

   h


Let me know if anyone has any ideas.

M
