@Task(nota) [2023-01-17] <x> {
    Make public :D
}

nota is a general-purpose notation language, with features tailored to human usage - think JSON, but for everyday, personal use cases. You can write nota standalone, or embed nota nodes in other files - say, in source code comments. For examples and usage, visit the repo's README.
The feature set is still increasing and the design of the language and its parser are subject to change. Please open issues or PRs to discuss or implement various ideas (or just to report bugs :P)
