Unlikely

[Trinitou]

the unlikely attribute is used in the clap-host repo but is C++20 or higher (so not C++17 friendly)

I guess it's good to define it here(?)
Or should it rather be in the clap-host repository?

I'd rather avoid it.
Because it doesn't have the same syntax in C and C++. I think in C you have to do __unlikely__((expr)).
Also clap itself almost ship no code so it doesn't need it.

clap-helpers could have it.

Ok, let's discuss it over there then.
