Subject: hash.collect

collect seems to work on a hash:

h = {'a'=>'1', 'b'=>'2'}

params = h.collect {|k, v| "#{k}=#{v}"}.join('&')

Yet collect isn't listed as a method of hash:
http://www.ruby-doc.org/core

Is it undocumented, or is some magic going on behind the scenes -- such 
as the hash getting converted to an array?

Thanks,
Joe
