Well, everything went well except for one thing, which was a bit irritating 
actually -- I couldn't find a way to concisely handle a block with either 
one argument (just the key) or two arguments (the key and the value). Seems 
like that should be doable in one block call using a splat. But I had to 
have a condition on arity and two separate each_pair calls, one for each 
case. Maybe it's just not possible.

In any case, thanks for your help! The code is looking much better.
