Several changes in one: (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.)
