That's exciting! I'm interested to hear about the language design. I vibecoded a unikernel web server a few weeks ago, and I've been trying to extend it into a full capability-secure microkernel called KokalOS.
The language borrows syntax from Python (and a wee bit from Haskell) and is essentially syntactic sugar over facilities provided by the runtime:
- statically typed from end to end
- closed and open/extensible types
- closed types are immutable, open ones have two variants: immutable and mutable
- arrays have two variants: immutable and mutable
- no OOP/classes. inheritance is nominal and mainly exists to provide access to class membership (is X a Y?)
- functions operating on data
- UFCS exists to provide nice features like "apple".substr(...)
- first class functions and closures
- monomorphized generics
- tailcalls
- operator overloading
- modules and namespaces to control access
- erlang/beam style first class processes. So you `spawn` a function and communicate between processes using send/recv instead of async/await
Processes are completely isolated at the runtime level. Each has its own stack, heap, mailbox and GC.
The bytecode carries all type information. The VM will compile using AOT-on-load.
My own runtime-becomes-a-os idea is still just an idea. I haven't really pursued it with seriousness. Will probably do that once the language and runtime stabilize.
