ocaml-jst VS P

Not just the standard library, but a whole ecosystem around it.

And their own compiler. https://github.com/ocaml-flambda/ocaml-jst

This Github proposal is also worth reading

From the post:

> Even without explicit mode annotations, the compiler can statically determine which variables may escape their enclosing region. Such variables are assigned the global mode; all others are automatically inferred to be local.

There's a little more info about mode inference in the proposal:

https://github.com/ocaml-flambda/ocaml-jst/blob/main/jane/do...

So arguments to "public functions" do require explicit annotations in order to be local, but otherwise the compiler is able to infer locality and this acts as a transparent optimization.

I worked on a state machine framework in another language, and have definitely have found less terse to be pretty good. Typing a few extra characters isn't that bad, especially if it makes some awful bit of evented code easier for someone to understand.

Of the things available open source, I think P-lang is pretty cool: https://github.com/p-org/P/blob/master/Tutorial/1_ClientServ...

Your proposed syntax reminded me of https://p-org.github.io/P/

I’ve gotten a lot of good about TLA+ and the more recent the P language has been really promising lately. It’s got a good pedigree and is being increasingly used as AWS as well.

I tried to use TLA+ but what annoys me the most is the disconnection between the actual implementation and its code. I think the P language has a much better future just because it can generate code that works: https://github.com/p-org/P

It is tough.

My approach when learning new protocols like Raft or Paxos is to implement them in Pluscal (TLA+'s higher-level language) or P (https://github.com/p-org/P). I've found that helps separate the protocol-level concerns from the implementation-level concerns (sockets? wire format?) in a way that reduces the difficulty of learning the protocol.
