There is still a sorting problem (of sorts). jaguarundi [1] keeps 
failing intermittently like this:

*** 47,53 ****  return len(val)  $$;  SELECT test1arr(array['aa=>bb, cc=>NULL'::hstore, 'dd=>ee']);
! INFO:  [{'aa': 'bb', 'cc': None}, {'dd': 'ee'}]  CONTEXT:  PL/Python function "test1arr"   test1arr  ----------
--- 47,53 ----  return len(val)  $$;  SELECT test1arr(array['aa=>bb, cc=>NULL'::hstore, 'dd=>ee']);
! INFO:  [{'cc': None, 'aa': 'bb'}, {'dd': 'ee'}]  CONTEXT:  PL/Python function "test1arr"   test1arr  ----------

I cannot find any other animal that does the same, but I doubt it's due 
to CCA this time.

Should dict tests perhaps output sorted(thedict.items()) instead? 
Testing dict formatting could be done with single-item dicts.
