Indentation-based config languages really need to be retired. Unless you put in extra work to validate your config, they are just error prone and impractical. They don't compose (INI files do, btw), they need special editors to keep sane when copying and pasting. If you now add an invisible type layer on top of them, it doesn't get better, it actually gets worse. Now the interpretation of a value in the file not only depends on the literal interpretation by the human brain but on some type definition one needs to be aware of, adding a semantic interpretation that can be non-obvious. That is why we have micro-formats: they are obvious (mostly). http:// http:// 03-13-1980 123e4567-e89b-12d3-a456-426614174000 "I'm a string" There's a delicate balance between readability and correctness and safety. YAML et. al. are not hitting that balance. And if you really, constantly, need to edit config files and can't handle a format that prioritizes correctness over readability: Build a UI.
