PDL::NiceSlice - toward a nicer slicing syntax for PDL River stage three • 93 direct dependents • 102 total dependents

Slicing is a basic, extremely common operation, and PDL's "slice" in PDL::Slices method would be cumbersome to use in many cases. "PDL::NiceSlice" rectifies that by incorporating new slicing syntax directly into the language via a perl *source filter...
