I wanted to ask if there's any chance of improving the parsing
performance of JSON, YAML, TOML, and similar data formats. It's pretty
poor today.

That could be done in the core with C code, improved Lisp code,
integration with an external library, or a mix of those.

I don't know much about the others, but given the importance of JSON as data exchange and serialization format, I think it's worthwhile to invest some time here. I've implemented a wrapper around the json-c library (license: Expat/X11/MIT), resulting in significant speedups using the test data from https://github.com/miloyip/nativejson-benchmark: a factor of 3.9 to 6.4 for parsing, and a factor of 27 to 67 for serializing. If people agree that this is useful I can send a patch.
