star VS firefly-boot

my own language Star! enjoyability is one of my main goals with the language, along with the "powerful, productive, and predictable" line

This is actually done by several bootstrapped languages, such as Crystal, Nim, Raku, and even my own language Star

In Star, commas and newlines are analogous everywhere, even inside array literals. This actually solves the issue of trailing commas by not needing commas at all

I really like Nemerle's OOP+FP hybrid model, and I've taken a lot of it to heart while designing my language Star, which is similar in spirit.

Most languages are afraid to for some reason, most likely because it "breaks tradition" or whatever. The only languages I'm aware of that allow this are Hack (for C-like enums) and my language Star (for both C-like and OCaml-like enums)

It's currently a work-in-progress, mainly due to subtyping issues with generics (which I'm honestly too lazy to fix rn, focusing on other stuff first). the code is located here, although be aware that it's a bit messy lol

Making lots of progress on Star's typechecker, which has been very difficult due to its expansive type system. Although still not completely finished or useable, it does at least work a bit. Currently need to implement type variable expansion/substitution, "lazy" type refinement (because I have no clue what else to call it), and some basic support for existentials

I think this is referred to as partial or lazy initialization. I have this feature in my own language Star (which us null-safe), but I don't have an actual null literal for this purpose

Sure I guess, here's one for Star: ``` You appear to be advocating a new: [X] functional [X] imperative [X] object-oriented [ ] procedural [ ] stack-based [X] "multi-paradigm" [ ] lazy [ ] eager [X] statically-typed [ ] dynamically-typed [ ] pure [X] impure [ ] non-hygienic [ ] visual [X] beginner-friendly [ ] non-programmer-friendly [ ] completely incomprehensible programming language. Your language will not work. Here is why it will not work.

Hello, I'm the developer of the Star programming language, and I have some questions about how to typecheck several new/uncommon features that it has, and looking for feedback on it in general.

Firefly, curly braces:

I'm still working on Firefly, a language with first class capabilities.

Since there's no other way for `deleteDirectory` to obtain capabilities than to recieve them as arguments, `deleteDirectory` only has access to the file system.

> Do you have more to share, like resources about capability-safe languages, or your ongoing work?

I can share an example from the main function of the [self hosting Firefly compiler](https://github.com/Ahnfelt/firefly-boot/tree/master/compiler):

    main(system: System): Unit {

I'm working on Firefly, which will compile to JS once bootstrapping is complete (almost there).

Still working on typechecking Firefly with the help of a friend.

Working on the type inference for Firefly. I don't have a lot of free time at the moment, so it's coming along slowly.

Firefly uses object capabilities for enforcing purity:

In Firefly, this is done without macros:

Firefly - self hosting, working on the type inference.
