This is my experience too. I rewrite often and liberally, and even switch langs (on the side) to check if it can bring huge gains.

Why not? Programming languages are not a solved problem (or parsing, or diagnostics, or...). We are today, barely, getting practical solutions to how write safely, fast and ergonomic (for example, rust) and yet: - Compiling performance is a

Lurking here is the main problem, not only of python but of so many langs: Dependency on the C-ABI. EVERY interfacing with C sucks, even made on C! Hopefully web assembly become good enough to change that...

I'm in a similar dream, building from scratch a relational language (I wanna not only the UI of Access/excel but the power of FoxPro). The main block is funding. I could do it for life if it pay at least the bills, but how fund it

I don't like lisp, not code in lisp; not even a line.. and I have read TONS of lisp stuff. Why? The #1 reason: The lisp people have a lot of cool things to teach. One of the most obvious examples: https://www.infoq.com/

Yes. But "we" also include the c/c++/rust developers here. This is a puzzle that is hard to crack. WHY "system language" developers near always produce the MOST slow languages on earth (C, C++, Rust, ....). And

The |> operator I miss, but rust have a near similar feel with iterators: let a= [1, 2]; a.iter().filter(|x|..).map(|x|...) I think I'm more functional in a lot of areas where in F# can't (or don't know how).

One of the interesting effects of using rust is saving money! I also migrate a F#/.NET ecommerce backend and can run in less RAM/CPU that make my bills lower.
