Several changes in one:

Browse source 
(1) dictionaries/mappings now have attributes values() and items() as
well as keys(); at the C level, use the new function mappinggetnext()
to iterate over a dictionary.

(2) "class C(): ..." is now illegal; you must write "class C: ...".

(3) Class objects now know their own name (finally!); and minor
improvements to the way how classes, functions and methods are
represented as strings.

(4) Added an "access" statement and semantics.  (This is still
experimental -- as long as you don't use the keyword 'access' nothing
should be changed.)

Mapping object type -- mapping from object to object.
These functions set errno for errors. Functions mappingremove() and
mappinginsert() return nonzero for errors, getmappingsize() returns -1,
the others NULL. A successful call to mappinginsert() calls INCREF()
for the inserted item.
