More as a reason to try I have implemented a PDL::DeclareSlice available on my github at https://github.com/jberger/PDL-DeclareSlice of which all the important bits are in the module (should you not want to go through the rigmarole of Dist::Zilla). As I suspected it isn't a drop-in replacement, you need a keyword to initiate the slice. I'd be interested if there are comments and would this be something worth pursuing further. Its benefit is that it doen't use the source filter, of course I'm sure it has edge cases just like a source filter would have so perhaps thats not too much of an improvement. One more question, is there any real magic in the nslice method? For now all my sugar does is convert to a slice call (i.e., `sl $pdl(1:4)` to `$pdl->slice("1:4")`). What kind of FORALL did you have in mind?
