C++ : Polymorphic inheritance without vtable

Inheritance and Virtual Table are often used to create interface in C++ polymorphic class
What if ... there were another way to do this ?
easier, cleaner, faster and more reliable
This article explains how to use CRTP, [std::variant](https://en.cppreference.com/w/cpp/utility/variant and std::visit to increase code performance.

template <typename... Args>
std::vector<std::string> toStringVector(Args... args) {
	std::vector<std::string> result;
	auto initList = {args...};
	using T = typename decltype(initList)::value_type;
	std::vector<T> expanded{initList};
	result.resize(expanded.size());
	std::transform(expanded.begin(), expanded.end(), result.begin(), [](T value) { return std::to_string(value); });
	return result;
}

It was possible to allow Xcode to access shell environment variables like the following:

defaults write com.apple.dt.Xcode UseSanitizedBuildSystemEnvironment -bool NO

This doesn't work anymore unfortunatley for some reason, for me what works is to load xcode project with 'open xcode-project' from command line.
