Is there an argument for ambivalent function definitions other than "keyword" recycling (possibly in a mnemonic fashion)? I hadn't seen Dzaima's APL, thanks! I

Is there an argument for ambivalent function definitions other than "keyword" recycling (possibly in a mnemonic fashion)? I hadn't seen Dzaima's APL, thanks! I like that he made a processing binding; APL always seemed like it would be such an obvious choice for doing dweet style graphics code golfing that I wondered why no one seemed to be doing it. A web-based APL would be a better choice though.

Natural language is also context-sensitive, so we are well-equipped to parse such formations; and they allow us to reuse information. The monadic and dyadic forms of '-' are related, so it's less cognitive overhead to recognize its meaning. 1. https://gitlab.com/n9n/apl https://gitlab.com/n9n/apl

Keyboard space is another somewhat important factor. My layout for dzaima/APL already uses all altgr keys, so I could definitely not afford multiplying the number of needed characters by 2. Not having ambivalently callable operators would also mean needing 2 versions of most of them. dzaima/APL being written in Java means getting it to run in a browser would be a bit hard, and ngn has given up on ngn/apl, but BQN[0] could definitely get a web canvas based graphics interface. Somewhat interesting to add to the conversation about Under is that, in my impl, calling a function, calling its inverse, or doing something under it (i.e. structural under) are all equally valid ways to "use" a function, it's just a "coincidence" that there's direct syntax for invoking only one. (Dyalog does not yet have under, but it definitely is planned.) 0. https://mlochbaum.github.io/BQN/ https://mlochbaum.github.io/BQN/
