Description
when i use vs2022, Something went wrong！ when I define hana struct like this:
struct Person {
BOOST_HANA_DEFINE_STRUCT(Person,
(std::string, name),
(unsigned short, age)
);
Person john{ "John", 30 };
boost::hana::find(john, BOOST_HANA_STRING("name")) == boost::hana::just("John");
};
Error !!
