Hi Ian,
I apologize for trying your patience with the badly written code
example. All objects were meant to be ThirdParty(), the demo was only
to show how a slice() filter could have been applied for the reasons
PEP357 made index() to exist.
eg: because numpy items passed to __getitems__ via slice syntax [::]
were illegal values.
PEP 357 is the one who specifically mentioned Numpy types -- which is
the only reason I used the name in the example; I could have just as
well used a string.
I am fully aware of what numpy does -- I have used it; modified the
fortran interfaces underneath, etc.
The index() method, however, affects *all* list objects in Python, not
just Numpy's -- correct?
I'll write a working piece of code tomorrow to demonstrate the filter
very clearly rather than a skeleton, and test it before posting.
