6.0.1
Release to get Pillow 9.2 dependency added for Python 3.7+
Note that future releases in the 6.1 or 7.0 range will drop support for Python 3.6.
Some Pattern-matching code gone over to add type annotations and to start documenting its behavior and characteristics. Function
attributes are now examined and stored at the time of Pattern-object creation rather than at evaluation time. This better matches WMA behavior which pulls out attribute this even earlier than this. These changes speed up doctest running time by about 7% under Pyston.
Combinatorica version upgraded from 0.9 (circa 1992) to 0.91 (circa 1995) which closer matches the published book.
Random Builtin function documentation gone over to conform to current documentation style.
