What could be described as Numpy for Perl, PDL was released in 1996 and is now seeing a resurgence of interest. The Advent Calendar showcases some of its features in a festive mood.

Where do you see that happening? I would like to see such thing, but my own experience and the general feeling is that this is not within reach.

For me, it's the acceleration of development in the last 5 years as seen in the Changes file. It's now releasing new versions almost every month.

Is it ported to Raku already?

Nothing stopping anyone from using Inline::Perl or NativeCall [0]. I'd like to see Raku's concurrency model working on these data structures. Otherwise there's always PDL::ParallelCPU [1]

For these kind of cases, guix looks like the best platform to set PDL under either an ad-hoc environment or a container, and much lighter and secure than Docker itself.
