don't forget your fourth option: chronos

Ecosystem-wise - a brief subset of Nim packages:

    https://github.com/ringabout/awesome-nim

One can, of course, go much further than simply distinct number types: https://github.com/ringabout/awesome-nim#science

(Unchained seems maybe the most featureful of those units packages.)

> This is useful for compiler programmers, or maybe also those writing source code analyzers/optimizers, but is that it?

It is also useful for anyone wanting to implement language-level features as simple libraries. Someone else brought up Nim here: it's a great example of what can be done with metaprogramming (and in a non-Lisp language) as it intentionally sticks to a small-but-extendable-core design.

There's macro-based libraries that implement the following, with all the elegance of a compiler feature: traits, interfaces, classes, typeclasses, contracts, Result types, HTML (and other) DSLs, syntax sugar for a variety of things (notably anonymous functions `=>` and Option types `?`), pattern matching (now in the compiler), method cascading, async/await, and more that I'm forgetting.

Just under their table of contents, they say that "This list is fairly outdated." and point you to https://github.com/xflywind/awesome-nim - and that repo seems to have recent updates.

Thanks for making these, I actually had no idea these existed! I don't "need" them now but seeing these gives me ideas for projects and makes future things easier.

I wish discovery of community libraries was higher, I'm constantly discovering libraries that do amazing things 'hidden' away. I know there's https://nimble.directory/ and https://github.com/xflywind/awesome-nim but most of the time I end up using a search engine for something specific if I think of it.
