Hi,
I can confirm that the cast-variants don't prevent the warning. "return !!
*prev_ptr;" and "return *prev_ptr? true: false;" both seem to work.
Back to the main topic: I find it quite unsatisfiying that there is seems to be
no way to avoid searching for the same position twice
("get_bucket", "find_iterator"). I don't see where the hint-version of insert
could be of any use, especially since the standard says "Implementations are
permitted to ignore the hint". I would need a function like "insert_if" taking
a predicate that decides whether to insert when an object with the same key
already exists.
