Type/class unification and new-style classes
+- New-style classes are now dynamic by default. Previous, they were
+ static (meaning class attributes could not be assigned to) and
+ dynamic classes had to be requested by adding __dynamic__ = 1 to the
+ body of the class or to the module. Static classes are faster than
+ dynamic classes, but dynamic classes are now at most 50% slower than
+ static classes; previously, they could be up to 10x slower. (This
+ was accomplished by making dynamic classes faster, not by making
+ static classes slower. :-) Note that according to one benchmark,
+ static classes are about the same speed as classic classes.
+
- C.__doc__ now works as expected for new-style classes (in 2.2a4 it
always returned None, even when there was a class docstring).
