The slicing stuff is closely married to the PDL Core internals.
Perhaps Craig who wrote the range related stuff might currently be the
best source of info.
It might also help if you spell out to us what kind of slice you are
after. There are typically several ways to attack this...

I have a slicing operation that's really tedious to do at the perl

slicing function. Then I looked at slices.pd. Holy cow.
(Incidentally, if I ever get numerical regular expressions in place,
the slice I need to perform at the moment would be super easy to
specify. But, it's barely more than a specification at the moment...)
I know that slicing operations are not documented, but where can I
find decent example code? Are there any good test files that check
how PP processes slicing operations? At the moment, slices.pd and
the PP.pm appear to be my only sources of information on the topic.
Thanks.
