How do you write this, not conceptually but physically. Do you have a char picker open at all times?

Haha, you can do it that way, in fact the online Uiua Pad editor has all the operators listed along the top.

But all the operators have ascii names, so you can type e.g. IsSmall = reduce mul mul fork(>0|<4) abs drop neg 1 - rot 1 dup and the formatter will reduce that to IsSmall ← /××⊃(>0|<4)⌵↘¯1-↻1. whenever you save or execute code.

That works in the Pad, and you can enable similar functionality in other editors.

I like to assume people using array programming languages just have a crystal ball that they use to call upon magic runes on the screen
