Changes (by robertwb):

  * status:  needs_review => needs_work


Comment:

 a_attrib will be defined after any non-empty loop even if it doesn't break
 with a match

 I think that this interface is rather subtle, I'd rather have a
 compare_using_identiy=[True|False] keyword in the function (which will
 iterate over the dictionary rather than indexing into it). On that note,
 is indexing ever safe (do equal ideals always hash the same?)
