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.
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 , and type-dependent operators (or polymorphic operators?). They are really intriguing.  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.
I spotted a typo in your blog post.
When you start talking about code on pizza boxes, you can read “Anyway, writing code by hand is very due for a serious experimentation.”, there's something missing between "very" and "due" :)
Edit: I added "much".
