platonic VS Nim

> Ya I don't think this is a good definition of dependent type - the prototypical example of a dependent type is a k-length vector.

Yah that's why I qualified my statement as dependent type like setup as I don't know a good definition of dependent types which I really grok and I've only briefly dabbled in it. It'd be awesome if you could point out a good resource showing a clear example / simple proof.

Well I started working on statically typed vector concepts [1]. The compiler can't do `proc concat[N,M: static int](v1: Vector[N], v2: Vector[M}): Vector[N+M]` and it fails. It might be able to be implemented via a macro like `proc concat(v1: Vector[N], v2: Vector[M}): typeFromSumOf(N,M)`, but I haven't tried yet.

Also just using static ints would require specific values at some point to work I think. Whereas you'd really want "induction" of some sort. Maybe a SAT solver would be required at that point? There's DrNim [2] which does tie Z3 but it's sorta dormant.

> Um yes this is literally what I was asking with respect to top ⊤.

Ah, I didn't know what you meant by top T.

> ya the negation is interesting - I wonder how it's implemented.

Nim's VM runs from Nim AST, so probably running it as a VM expression.

22. Nim - $80,000

I think the right answer to your question would be NimLang[0]. In reality, if you're seeking to use this in any enterprise context, you'd most likely want to select the subset of C++ that makes sense for you or just use C#.

I don't think it's a rust-inspired language, but since it has strong typing and compiles to javascript, did you give a look at nim [0] ?

For what it takes, I find the language very expressive without the verbosity in rust that reminds me java. And it is also very flexible.

I see a valid cert for https://nim-lang.org/

FYI, on the front page, https://nim-lang.org, in large type you have this:

> Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula.

You better off with using a compiled language.

If you interested in a language that's compiled, fast, but as easy and pleasant as Python - I'd recommend you take a look at [Nim](https://nim-lang.org).

And to prove what Nim's capable of - here's a cool repo with 100+ cli apps someone wrote in Nim: [c-blake/bu](https://github.com/c-blake/bu)

Chapel has at least several full-time developers at Cray/HPE and (I think) the US national labs, and has had some for almost two decades. That's much more than $100k.

Chapel is also just one of many other projects broadly interested in developing new programming languages for "high performance" programming. Out of that large field, Chapel is not especially related to the specific ideas or design goals of Mojo. Much more related are things like Codon (https://exaloop.io), and the metaprogramming models in Terra (https://terralang.org), Nim (https://nim-lang.org), and Zig (https://ziglang.org).

But Chapel is great! It has a lot of good ideas, especially for distributed-memory programming, which is its historical focus. It is more related to Legion (https://legion.stanford.edu, https://regent-lang.org), parallel & distributed Fortran, ZPL, etc.
