Hi Paul- This is very intriguing work. PDL as a module is focused on efficiently calculating for numerical computation. Ability to compute with more general PDF objects would be very interesting to the PDL community.
Specifically, the coming PDL3 refactoring to a more general, flexible, and extended type system would have a natural fit for the types of objects this work could generate. Another goal for PDL3 is JIT compile support for computation which might be exactly the place where this PDF language work could tie in with computation. The PDL home page is at http://pdl.perl.org and I invite you to join the perldl mailing list which is the best way to ask questions and get help or discuss things PDL related. You can sign up here: http://mailman.jach.hawaii.edu/mailman/listinfo/perldl To get back on topic, it looks like there is a fair amount of other related work in this area that may be relevant in choosing a module name. Has some of this been implemented for R or in a Python package. That might give some other data points. --Chris On Fri, Jul 25, 2014 at 10:49 AM, Paul Bennett <paul.w.benn...@gmail.com> wrote: > Hi, Maggie and John, > > On Fri, Jul 25, 2014 at 10:39 AM, John M Gamble <jgam...@ripco.com> wrote: >> On 7/25/2014 8:48 AM, Maggie X wrote: >> >> Thanks for looping me in, David!
