Previous post (part 1) on HN: https://news.ycombinator.com/item?id=27576937 https://news.ycombinator.com/item?id=27576937 Second post introduces Fluent, an APL/J/BQN/LPA-inspired programming language that is used for a computerized paper&pencil programming, a REPL for your pencil. Aim of Fluent is to be extremely easy to read and write, i.e. LTR, only binary infix ops, no tacit, higher-order ops are fine, also optional right paren.

This looks really nice, and I'd love to try it. I am steadily becoming more convinced that there's room for an LTR APLish language.

  Hello Adám, thank you for the LPA notes – they are still very inspirational and reassured me that LTR is worth exploring. If you found out something new, I would love to read it. I am aiming private beta for the end of 09/2021. The language, runtime and interface are in a good shape, however the handwriting recognition have seen only my glyphs so far. Also segmentation algorithm is something to think about when writing. I have to solve these issues before private beta and I have only vague ideas about that right now. Language-wise, I have to explore monadic operators [0], and type-dependent operators (or polymorphic operators?). They are really intriguing. [1] These facilities should be enough for the language, and then I have to fit operators into this paradigm. Even though pencil enable us to use every glyph, I try avoid unfamiliar/complicated ones. Polymorphic operators could really help here, as one operator could have multiple roles. However, I try to be vigilant because it could create bigger mess than monads/dyads.
