firefly-boot VS Cwerg

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.

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.

Perhaps these have already been dealt with and I'm missing critical information. If so, my apologies. Great work, in any case.

Cwerg has backend that can be used as JIT and is written with readability in mind. Additional documentation can be found here: https://github.com/robertmuth/Cwerg/tree/master/Docs

I defined a basic ISA-like IR for Cwerg. It has unlimited registers and no constraints on immediates.

I was also going down the path of bike shedding concrete syntax for my language Cwerg before pulling the plug on that effort and just using s-exprs. I managed to make the s-expr quite succinct by carefully choosing the order of arguments so I can omit optional ones. Also very helpful was to use square brackets for list, e.g. (call fun-name [arg1 arg2]). This simplifies parsing a little bit and is easier on the eye. Here are some Code Examples

I am iterating over the languages features for Cwerg's Frontend which aims to be a low level language with about the complexity of C but with some of the comforts of modern languages. I am especially happy with the choice of adding sum types. Relative to C the current feature set looks like this: Removed: * arrays decay to pointers * bitfields * separate compilation (more of a backend issue) * pre-processor * varargs * implcit type conversions * (untagged) unions * ++/-- * comma operator * implicitly nullable pointers * goto
