pen VS gluon

The Pen programming language is a new parallel, concurrent, statically typed, functional programming language. I'm excited to announce its v0.4 release here!

In this post, I describe my experience and some caveats about implementing and gaining benefits from the Perceus RC. I've been developing a programming language called Pen and implemented a large part of the Perceus RC there. I hope this post helps someone who is implementing the algorithm or even deciding if it's worth implementing it in their own languages.

I'm a developer of the Pen programming language. Since the last v0.3 release, many features have been implemented including async/await and concurrent runtime.

A colleague of mine used https://github.com/gluon-lang/gluon with great success in our rust projects. Although it probably can't run in a no_std environment.

Aside from these, if you want some inspiration for a production-grade language built in Rust, you might want to go through the source code of Starlark and Gluon.

Some languages, like Zig and Gluon have an import expression, where the imported symbols are under a local constant's name. Gluon then also supports destructuring, and Zig has had multiple proposals for years about it, none of which are canon. That is, code like this:

This should be a good use-case for rust-based scripting languages, I think.

I loosely followed a project of that kind a while ago, I don't quite remember if it was Gluon [0] or Dyon [1]. Not sure if these are still active, or if another competitor showed up in meantime.

Or if you wanted something more Rust-native, you could try Gluon.
