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

Insert the specified `value` into this set if a key equivalent to `value` does not already exist in this set; otherwise, if a key equivalent to `value` already exists in this set, this method has no effect. `value` is left in a valid but unspecified state. Return a pair whose `first` member is an iterator referring to the (possibly newly inserted) `value_type` object in this set that is equivalent to `value`, and whose `second` member is `true` if a new value was inserted, and `false` if the key was already present.
