Increments or decrements each of the underlying is_... iterators in the underlying tuple-like object current_.

1) Equivalent to /*tuple-for-each*/([](auto& i) { ++i; }, current_); return *this;
2) Equivalent to ++*this;
3) Equivalent to auto tmp = *this; ++*this; return tmp;
4) Equivalent to /*tuple-for-each*/([](auto& i) { --i; }, current_); return *this;
5) Equivalent to auto tmp = *this; --*this; return tmp;
6) Equivalent to /*tuple-for-each*/([&]<class I>(I& i) { i += iter_difference_t<I>(x); }, current_); return *this;
7) Equivalent to /*tuple-for-each*/([&]<class I>(I& i) { i -= iter_difference_t<I>(x); }, current_); return *this;

Parameters

n - position relative to current location

Return value

1,4,6,7) *this
2) (none)
3,5) a copy of *this that was made before the change
