Example



import <concepts>;

import cmoon.meta;

struct 
{
    template<std::integral T>
    constexpr bool operator()(T t) const noexcept
    {
        return t % 2 == 0;
    }
} is_even {};

int main()
{
    using vl = cmoon::meta::value_list<2, 3, 3>;

    static_assert(vl::any_of(is_even));
}
