 code. Also, it makes the implementation of some types of iterators more complicated. Any iterator
 that has members that are not default constructible (e.g., an iterator that contains a lambda that
 has captured by reference) must take special steps to provide default-constructibility (e.g.,
-by wrapping non-default-constructible types in \tcode{std::optional}). This can weaken class
-invariants.

 The guarantee of default-constructibility simplifies the implementation of much iterator- and
