What happens when both overloads of `serialize` are visible and you call `serialize(42)` where 42 is an int?

template <typename T> std::enable_if_t<std::is_integral_v<T>, void> serialize(T) { /* (A) integral */ } template <typename T> std::enable_if_t<std::is_floating_point_v<T>, void> serialize(T) { /* (B) float */ }
