Forcing std::vector overload instead of int overload on list with one element

Question

Consider the code below:

#include 
#include 

void f(std::vector v) {std::cout << __PRETTY_FUNCTION__ <<         


        

Answer 1

Forcing std::vector overload

int main()
{
    f(std::vector{42}); // the vector overload is being picked up now
}

Why isn't the vector(initializer_list) constructor being picked up?

Assume that another header declares a void f(std::set v).

How would you like the compiler to react when faced with f({1}): construct a vector or construct a set?
