@Pavel Golfier? No, just better. I'm proposing a notation which allows even rank, nut just depth, as currently. I'm also proposing a notation similar to JSON for APL objects ("namespaces"), and a couple of other things. I already made APL golfier with ⊆ which is {(,~~⍵)/,⍳⍴⍵} in version 16.0.
Although I guess my new notation can save space sometimes.
@Pavel You don't have to. There is always a language bar you can use to enter APL symbols, and if you use the RIDE interface, you can enter keywords that are then auto-translated to symbols. That being said, I learned the entire keyboard in an hour when I was 12. I'm sure I could teach you most of it very quickly.
@Pavel Even for non-students. The personal licence is completely free.
@Pavel Personal and Educational. They are completely equivalent. We only have both because the personal one used to have a small fee, but now they are both free. I hope to convince management to give up on the registration soon.
