compound::iterator isn't far from a forward_iterator, and if we want to use it with std::ranges, we have to upgrade it. This is because std::ranges::subrange() only provides front() for forward ranges, and we do use this front(). Boost apparently isn't as strict. To make it a forward_range, we have to drop operator-> and make operator* return a value (similar to std::views::tranform), since forward iterators require that pointers and references be stable, and this iterator returns a pointer to one of its members. We also add an iterator_concept member to declare the compatibility to std::ranges.
