Something like this?

>> h = Hash.new( [] )
=> {}
>> h["a"] << 2.2
=> [2.2]
>> h["a"] << 3
=> [2.2, 3]
>> sum_of_a = 0.0
=> 0.0
>> h["a"].inject { |sum_of_a, value| sum_of_a += value }
=> 5.2
>> sum_of_a
=> 5.2

I have no idea if that's the best way to do that; I'm still earning my Ruby
chops.

Craig
