Nvm, it works now.

in my apl (f ⋄ g ⋄ h) means ((f) (g) (h)), i.e. just a way of saving parens. would it be worth it changing it to ((⊂f),(⊂g),(⊂h)), i.e. the results of all the functions in an array?

@dzaima Sounds like mapping over an array of functions. Definitely a nice-to-have.

Actually J has an operator to create an "array of functions", and J uses it in many different ways where an array of functions can be useful.

Btw, does anyone have EBNF syntax of Dyalog APL (or anything close)?
