Basic C++11 template variant type.

zlib license and all that goodness

I make use of tagged unions quite a lot, and I wanted a variant type to handle all the boilerplate I write, at least during prototyping, so I did this weekend project that essentially taught me that C++'s template metaprogramming sucks.  In my opinion, Clay ( is a lot nicer for this type of thing, but it already has a variant type built-in.

I might try and get rid of the use of std::type_index in favor of a length-dependent type-unique integer type using more template metaprogramming magic, but std::type_index works for now.

Usage example:

#include "Variant.hpp"
#include <iostream>

int main(int argc, const char * argv[])
	typedef Variant<const char*, int, float> V;
	V value(float(100));
	V value2 = value;
	value = V(int(0));
		std::cout <<<int>() << std::endl;
	else if(<float>())
		std::cout <<<float>() << std::endl;
	else if(<const char*>())
		std::cout <<<const char*>() << std::endl;
	return 0;
