Exactly, the PEP does not reflect the reality of what anybody wants in
the core. It needs modification, or replacment. Can I just do that?
Or do I need permission from Barrett and others who has only a passing
interest in this anymore.

I think you misunderstood my meaning. For example Numeric has lived 10
years with very few changes. It seems to me it is rather stable.

It actually is pretty clear to many. There have been a wide variety of
modules written on top of Numeric and Numarray. Most of the rough
spots around the edges have been ironed out. Our arguments now are
about packaging other code living on top of an arrayobject.
Thanks for your help,
