:relfileprefix: ../../
:mrdocs:

Insert the specified `value` into this multiset (in amortized constant time if the specified `hint` is a valid immediate successor to `value`). `value` is left in a valid but unspecified state. Return an iterator referring to the newly inserted `value_type` object in this multiset that is equivalent to `value`. If `hint` is not a valid immediate successor to `value`, this operation has `O[log(N)]` complexity, where `N` is the size of this multiset. This method requires that the (template parameter) type `KEY` be `move‐insertable` into this multiset (see {Requirements on `KEY`}). The behavior is undefined unless `hint` is an iterator in the range `[begin() .. end()]` (both endpoints included).
