What Hacker News says
3 sources> A language with dependent types and borrow checking
I'm definitely interested in this! There are significant challenges here though, particularly with respect to combining dependent types with effects and coeffects! This is open research, but significant progress is being made, and I'm hopeful. I'm currently keeping an eye on https://github.com/granule-project/granule, which seems like it might have some interesting things to say about this.
Currently I'm trying to learn how to implement dependent types in my programming language, Pikelet: https://github.com/pikelet-lang/pikelet (currently doing a rebuild of the front-end in https://github.com/brendanzab/rust-nbe-for-mltt). I'm hoping that once I've done this I might eventually be able to start looking at implementing something to do with borrow checking in it, but who knows! The more I

> Idris is perhaps the most famous dependently typed language.
I'd probably put Coq and Agda ahead of Idris in terms of being well known and established, but Idris is certainly pretty cool in how it tries to target practical programming.
They've been historically hard to implement in a way that is both efficient, sound, integrates with effectful code, promotes code reuse (like in Haskell), and has good developer UX (good error messages and IDE support). I believe we are getting to a point where it is feasible, hence I'm messing around with it myself [0], but it can be challenging to navigate the terrain of papers and theory as a language designer. While DTs themselves are quite simple, the integration with other features users expect is tricky, and producing a production-grade compiler is definitly not as straightforward as making a regular Hindley-Milner style language.
