bsl::list::insert

Insert at the specified dstPosition in this list the values in the range starting at the specified first and ending immediately before the specified last iterators of the (template parameter) type INPUT_ITERATOR, and return an iterator providing modifiable access to the first element in the newly inserted sequence of elements. The (template parameter) type INPUT_ITERATOR shall meet the requirements of an input iterator defined in the C++11 standard [input.iterators]providing access to values of a type convertible to value_type, and value_type must be emplace‐constructible from *i into this list, where i is a dereferenceable iterator in the range [first .. last)] (see {Requirements on VALUE}). The behavior is undefined unless dstPosition is an iterator in the range [cbegin() .. cend()] (both endpoints included), and first and last refer to a sequence of valid values where first is at a position at or before last.
