Very interesting. I wish I could read a copy of that without paying CHF 198.

This feels like far less than the full set of APL operators, though.

Sure. All the element-by-element operators like matrix addition and Hadamard multiplication are just special cases of array-map, for one thing, so that whole chapter could be left out. Fold generalizes both reduce and scan. Things like iota and reshape are already available as one-liners. Everything that depends on numeric operations, like matrix divide, I omitted. And so on.
