I have been using (_badly_) [Emacs](https://www.gnu.org/software/emacs/) since around 2008.

This article is a reinterpretation of an [article](https://github.com/xvw/planet/blob/master/content/posts/notion-cafe.org) I wrote in 2021 on my [former site](https://github.com/xvw/planet).

I started using the [OCaml](https://ocaml.org) language regularly around 2012, and since then, my interest and enthusiasm for this language have only grown.

_Tetra Master_ is the optional card game in **Final Fantasy IX**.

The [OCaml](https://ocaml.org) module system can be intimidating, and it typically involves the use of many keywords—for example, `open` and `include`, which allow importing definitions into a module.

**Guarded methods** allow attaching **constraints** to the receiver (`self`) **only for certain methods**, thus allowing these methods to be called only if the receiver satisfies these constraints (these _guards_).
