Recently I end up using structs everywhere as functions parameters to basically get named function parameters and better default arguments. Are there any downsides to this? So far the only annoying thing is to have to define those structs.

struct FunParams{
    int i = 5;
    float f = 3.14f;
    std::string s = "hello";
};

void Fun(const FunParams& params){}

int main(){
    Fun({.s = "hi there"});
}

I'm sure you can come up with some utility class required (templated with T, Lemmy won't let me) that isn't default constructible but can be implicitly constructed from a T, then use this instead of type T in the struct definition.
