error: no member named 'get_pointer' with std::variant

[alanjohnjames]

I am getting compiler errors when using simple_match on a std::variant

[build] /Users/alan/Git/simple_match/include/simple_match/implementation/some_none.hpp:120:73: error: no member named 'get_pointer' in 'simple_match::customization::pointer_getter<std::__1::variant<X, Y> >' [build] auto ptr = customization::pointer_getter<std::decay_t<T>>::template get_pointer<Class>(std::forward<T>(t));

Here is the code sample;

struct X { int _x; X(int x) : _x(x) {}; };
struct Y { int _y; Y(int y) : _y(y) {}; };

using XY = std::variant<X, Y>;

std::string eval(const XY& v) {
	using namespace simple_match;
	using namespace simple_match::placeholders;

	return match(v,
		some<X>(), [](auto&& x) { return "Found variant Y";},
		some<Y>(), [](auto&& y) { return "Found variant X";}
    );
}

void test_variant() {
	XY xy{ X(2) };
    const auto & eval(xy);
}

This code sample is based on the math_variant_t example in test.cpp only without the variant recursive wrapper and of course without Boost.

Could anyone please help ?
Am I using simple_match correctly ?

Many thanks in advance.
