Suppose that you want to roll a 6-sided die in APL. That's trivial: ?6 0 ?6 4 ?6 0 ?6 3 Now suppose that you wanted to roll a bunch of times. APL naturally scales, since the "roll" function ? is a primitive scalar function: ?10⍴6 1 5 5 2| Fastidious Elegance

Here's the CFP for ARRAY '25 this year! Dear all We are organising ARRAY'25 which is co-located with PLDI'25. This workshop is dedicated to array programming, which is interpreted very liberally. We are interested in classical array programming a la APL, array theories, semantics, verification, type systems, compiler optimisations, parallel| Fastidious Elegance

I was thankfully informed by Douglas Mennella that the before and after diagrams for section 3.7 of my thesis don't make sense, and I agree.

Two major principles emerge in APL programming, suggestivity and idioms. I recently encountered a nice illustration of how these two concepts work together. This demonstrates how the use of compositionality in the service of suggestivity ca help to improve and enhance the communicative and expressive power of idiomatic notation, which| Fastidious Elegance
Previously, Co-dfns could only support ranks <= 4. Now, the architecture supports arbitrarily large array sizes, though this is only partially used in various primitives. See the release notes for more details. However, this is a bigger deal than it might seem, as it opens up a number of new features| Fastidious Elegance
