### Examples ### More examples
You can follow some example usage in the [examples/](examples]) folder. In [examples/core](examples/core/), we build up some functionality, starting from drawing one sample and finishing with a replication of [Dissolving the Fermi paradox](https://arxiv.org/abs/1806.02404). In [examples/more](examples/more), we present a few more complicated examples, like finding confidence intervals, a model of nuclear war, an estimate of how much exercise to do to lose 10kg, or an example using parallelism.

- I offer no guarantees about stability, correctness, performance, etc. I might, for instance, abandon the version in C and rewrite it in Zig, Nim, Rust, Go. - I offer no guarantees about stability, correctness, performance, etc. I might, for instance, abandon the version in C and rewrite it in Zig, Nim, Rust, Go.

- I am conflicted about parallelism. It *does* add more complexity, complexity that you can be bitten by if you are not careful and don't understand it. And this conflicts with the initial grug-brain motivation. At the same time, it is clever, and it is nice, and I like it a lot. - I am conflicted about parallelism.

The bailey: The good:
- You can vendor the code, i.e., save it as a dependency together with your other files. This way, this renders you immune to any changes I may make. - You can vendor the code, i.e., save it as a dependency together with your other files. This way, this renders you immune to any changes I may make.
