I haven't decided if I'll actually go through with it, but as a learning experience, I've been thinking about making little rewrites of some command line utilities (and maybe some original ones if I get any ideas) that output NestedText, instead of normal unstructured text. NestedText looks like a really cool data format. It's basically exactly what I wished Yaml was, and the reference implementation is in Python so maybe it could be fun. Plus it'd give me a reason to try out the really cool looking Typer library.
