Subject: Hash.new with a block?

Hi,

In the code:

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

what method is yielding the values hash, key to the code block?  It
doesn't seem like it could be new() since new() isn't called when you
lookup a key in a hash.  Does new() somehow associate that block with
the method [] in Hash?

Thanks.
