plum VS Nim

You can use https://github.com/beartype/plum instead of that elif chain too

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.

Perhaps the Nim Github Wiki would be more to your liking? https://github.com/nim-lang/Nim/wiki

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.

20 milliseconds? On my 7 year old Linux box, this little Nim program https://github.com/c-blake/bu/blob/main/wsz.nim runs to completion in 275 microseconds when fully statically linked with musl libc on Linux. That's with a stripped environment (with `env -i`). It takes more like 318 microseconds with my usual 54 environment variables. The program only does about 17 system calls, though.

Additionally, https://github.com/c-blake/cligen makes decent CLI tools a real breeze. If you like some of Go's qualities but the language seems too limited, you might like Nim: https://nim-lang.org. I generally find getting good performance much less of a challenge with Nim, but Nim is undeniably less well known with a smaller ecosystem and less corporate backing.

On Unix, you might try Nim (https://nim-lang.org) with https://github.com/Vindaar/shell and there are a slew of pipeline-y/Unix-y utilities over at https://github.com/c-blake/bu

Nim is statically typed and (generally) native-compiled, but it has very low ceremony ergonomics and a powerful compile-time macro/template system as well as user-defined operators (e.g., you can use `+-` to make a constructor for uncertain values so that `9 +- 2` builds a typed object.

> If only there was a clean fast bare-metal language to write all this in..

The author includes a footnotes for "BUT RUST.." and "BUT ZIG..", but how about Nim? Looks like there is a native library implementation of `lowerBound` https://github.com/nim-lang/Nim/blob/version-2-0/lib/pure/al...

Same ideas are used in Nim's incremental compilation (wip) https://github.com/nim-lang/Nim/tree/devel/compiler/ic
