Is the following correct?
class X { public: X(int, double); };
std::vector<double> vec; int i = 10; double d = 2.5; X x;
tuple<construct, _a&, _b, _c> t1(vec, i, d); tuple<construct, _a&, _b, _c> t2(x, i, d); any<construct, _a> v1(get<1>(t1), get<2>(t1)); any<construct, _a> v2(get<1>(t2), get<2>(t2));
If yes, how v1 is bound to vec and v2 to x?
It isn't. v1 stores a std::vector<double> which is constructed in place and is not related to vec in any way. v2 again hold a separate object of type X, which is created using X(int, double). In Christ, Steven Watanabe
