eve VS dejavu

C++ offers tools for writing better APIs, and since the addition of concepts in C++20 it offers much better API enforcement. Writing an equivalent to libraries such as {fmt} or EVE is not possible in anything we’d call C.

Here is a doc on how we suggest to do it: https://jfalcou.github.io/eve/multiarch.html Here is complete code of that example: https://github.com/jfalcou/eve/tree/main/examples/multi-arch

My source for this was the statement:

Indeed you cannot. Then again, you couldn't write a library like fmtlib in C in the first place. I mean why do you complain about C++ features which enable you to write libraries you otherwise couldn't? How would you expect to implement equivalent libraries to EVE or mp-units in C alone?

I will certainly admit that variadic generics and default initializers would be nice in some situations. For example there have been proposals to make #[derive(Default)] support default initializers, and I have a side project I could clean up a bit with variadic impls: https://github.com/rpjohnst/dejavu/blob/main/gml/src/vm/bind.rs. But it seems to balance out overall and I don't personally experience a need to write a bunch more code, let alone just to satisfy the compiler.
