I like the idea of mini-PDL modules with bundles to aggregate them for install. > PDL has suffered from several marketing problems, the single largest > of which is the difficulty of installation.

A good generic 2D plotting capability (to go with the new, generic---or at least portable TriD) would be wonderful. > PDL's great strength has been the PP core, which let PDL grow rapidly > into a full data reduction environment.

I've thought a code reading would be a good way to learn more about PDL internals and as a lead in to further PP development. --Chris > Er, just my $0.02 rant for the evening... > > > On Oct 28, 2009, at 10:09 PM, David Mertens wrote: > >> I don't know if anybody has pointed this out before, but on Monday >> night I stumbled across Numeric::LL_Array.
