I have a slicing operation that's really tedious to do at the perl level. I thought to myself, "It can't be that hard to write a PP'd 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. David
