I'm making a programming language, need criticism

I've been trying to make a programming language for a while. I'm trying to make it in Rust. I made the basic language. The intended problem it is solving is making a simple language like Python but can run code really fast. The program itself will have native tensors. Will have CUDA/GPU backend. I made a clone of numpy embedded in the language. Now I'm developing a pytorch clone for the language. So, I would like to know what other problems you want me to solve in the language. The semantics are not finalised yet. So, I am definitely open to take some opinions.

You're not the first person to think of that. Is there more to the idea?

i thought of using native tensor operations built inside the compiler. its like a programming language to design machine learning solutions and projects.

Literally just Mojo

you may be interested in checking out Mojo for ideas and inspiration

Yeah sureee. Thanks!

if you're writing an interpreter, it's not going to be faster than python + numpy (or a cuda equivalent, I guess), and its api is already about as ergonomic as gets. even if you are writing an actual compiler, it's not the driver code that's taking the bulk of your performance: it's either gpu compute or shuffling data back & forth. if speed and built-in tensors are your design goals, your project doesn't bring much utility to this space. sorry.

if you're doing this as a learning exercise, go for it! but don't use ai! if you manage to write a compiler for programs that run cuda kernels, we would love to see it! but using ai to create "cupy but worse" is a waste of your time and mine.

there is one interesting advantage that you didn't mention, though: you can run native binaries on systems that don't have python or cupy or whatever else installed. running a program on a cluster is kind of a pain when you have to manage the right versions of all sorts of different dependencies.

Really thanks for the feedback. i always thought that the language and api is the barrier to python's speed. This really helped. This is my first big project in compiler design. So, i am hoping i'll get a really good experience designing it

Simple like python in syntax, beats rust at safety, beats assembly at speed, C in binary size.

Design for that. Aim higher.

yeah suree

You should probably include a link to the spec and maybe a repo if you want feedback

Some features are still incomplete and under work. so the code is not public as of now. so i thought this is the right time to add more features that are really useful to the users and contributors
