Howdy,
simde is one of the most prominent users of the lovely Hedley but it seems the original author @nemequ (Thank you and, hi!) hasn't been very active for a number of years here.
I appreciate your maintenance of Hedley and have merged it into my little fork that adds ISPC support. Have you thought about maintaining a dedicated repository for your continuation of Hedley that would accept PRs?
Thinking even more ambitiously, I am interested in the possibility making hedley.h built from multiple files (e.g. one per compiler) using some sort of preprocessing step either using cpp, Python w/ TOML/YAML, basically anything but manually typing the boilerplate and messing up preprocessor conditional nesting. Adding just one compiler was annoying because of that but I've got more improvements I'd like to make if the process of editing hedley was easier.
Thanks,
Jevin
