there is a call of std::apply for std::tuple,

inside the lambda, there is another container: std::array, each element of that is an object and I need to call this member with a parameter – tuple value.

something like this:

std::apply(
    [this](auto&&... tuple_item) {
         ((std::get<TUPLE_ITEM_INDEX???>(this->my_std_array_member.func(tuple_item.name), ...)
    },
    my_std_tuple
);

of course, supposed that tuple and my_array_member are equal (size).
objects in a tuple are classes and all of those have a “name” field, which I need to use in array calls

how to get current tuple index in the expression to use it in get<>() for std::array ??
