Anyone considering using this should be strongly looking at using Swift or Rust instead. You can build almost any given language idea using the C macro preprocessor, but that doesn't mean it's a good idea to ship production code using it.

The worst codebases to inherit as a maintenance programmer are the ones where people got clever with the C preprocessor. Impossible to debug and impossible to maintain.

C99 is a stable target for writing bootstrappable software: there are multiple mature compiler implementations, at least one of which is bootstrappable down to hex0, and the bootstrap chain is not too long.

I find that most abuses of the preprocessor are by folks unwilling/unable to simplify their design into a form that's (a) native to the C language/runtime or (b) not repetitive to type.

This library on the other hand addresses a nasty papercut whose presence usually stops folks with modern language experience from choosing C when it might otherwise be valid. Plus you can't beat C's long-term stability.

Though I agree that 90+% who _think_ they still need C should probably move on to making Rust work for them, instead.
