:mrdocs:

Return an iterator providing modifiable access to the first (i.e., ordered least) `value_type` object in this set greater‐than or equal‐to the specified `key`, and the past‐the‐end iterator if this set does not contain a `value_type` object greater‐than or equal‐to `key`. Note that this function returns the _first_ position before which a `value_type` object equivalent to `key` could be inserted into the ordered sequence maintained by this set, while preserving its ordering.
