If I were to make my own programming language, it would look an awful lot like Python.

Roughly 100%.

I have only read the first end of the article but I can't help but think that a project like libriscv[0] would've/could've worked for their game project too because fun fact but the creator of librsicv, the legendary fwsgonzo is also making a game. I highly recommend for people to check out their discord server.

But my main point is that libriscv is one of the fastest libriscv emulators and then something like C/C++/lua could've been used with sandboxing purposes for the purposes of the game then.

Am I missing something? Although, making a programming language is one kind of its own projects and that's really cool as well :-D

but I would also love to hear the author's opinion on libriscv as it feels like it ticks of all the boxes from my understanding

this project is pretty interesting, although i'm wondering how they're planning to address the "easy sandboxing" design goal in a compiled language with raw pointer arithmetic and clib interop... in that regard i think lua would have been a lot easier to sandbox, despite the author's concerns.

(also, they might want to look into lua userdata, since that would address their concern about the overhead of converting between native and lua data structures. the language is designed to be embedded in C programs after all)

Making you own language is easy. Creating the library that will actually solve problems without forcing the developers to reinvent the wheel is the crux. There is a reason why C++ / Java / JavaScript etc are established, it's the already proven libraries around those languages that allows them to be so successful.
