I worked in the Mojo codebase for over a year, ask me anything =)

What are your thoughts on the negative reception Mojo has faced within the programming community, and how should the project move forward?

u/verdagon Vale 13d ago

My opinions on that might be a bit too spicy to speak aloud, because I was so close to it. Sorry! XD

Hey, thanks in advance. How doest it eliminate the GC? the borrow checker is not widely discussed as much as in the case of Rust. How does it compare to it?

u/verdagon Vale 14d ago

One can think of it like Rust's borrow checker with some ergonomic improvements, it's built on shared-xor-mutable just like Rust is.

Thoughts on Mojo vs Carbon vs Rust approaches for memory safety?

Is it possible to switch an existing Python backend with type annotations to this? What would I gain? Asking for a backend project.

u/verdagon Vale 13d ago

Depends what you mean by switched. If you want to call into Mojo code from Python, or Python to Mojo, that's something they're working on ~currently and some of that interop already works. If you want to migrate your typed Python code to Mojo, alas, that won't work any time soon.

u/AssOverflow12 12d ago

I meant the latter, meaning taking an existing Python codebase and instead of the standard Python toolchain, build it with Mojo. Similarly to how you could with JavaScript and TypeScript. Thank you for clearing that up!

What is the airspeed velocity of an unladen swallow?

u/verdagon Vale 13d ago

42 miles per hour, if it's a European swallow.

Did they end up shipping a memory unsafe compiler?

Do you foresee working on vale.dev in future? Or is it abandoned now? I really loved the posts there.
