Detailed Description

Helper class for calling function iteratively on parameter pack.

Used until C++17, which includes parameter pack folding. See: https://stackoverflow.com/a/17340003

// C++17 built-in folding expression
template<typename... Ts>
void CallFooOnAll(Ts&&... ts) {
    (foo(std::forward<Ts>(ts)), ...);
}
 
// C++11 "folding" using ExpandType
template<typename... Ts>
void CallFooOnAll(Ts&&... ts) {
    ExpandType{0, (foo(std::forward<Ts>(ts)), 0)...}
}
