This is my nearly two year old patch

[ 400998 ] experimental support for extended slicing on lists

somewhat spruced up and better tested than it was when I wrote it.

Includes docs & tests.  The whatsnew section needs expanding, and arrays
should support extended slices -- later.

+Ever since Python 1.4 the slice syntax has supported a third
+``stride'' argument, but the builtin sequence types have not supported
+this feature (it was initially included at the behest of the
+developers of the Numerical Python package).  This changes with Python
+2.3.

+% XXX examples, etc.
