return type of flat_map::emplace is not match to documents

[Kohei Takahashi <flast@…>]

The document says, return type of flat_map.emplace is pair that contains iterator and bool. However actual type is iterator.

e.g. Boost.Unordered and standard library of emplace return pair. container::map::emplace returns iterator (map's doc is match to impl).

Which is correct?

This is a bug, the standard library is correct. Fixed in trunk.

Merged to release branch

Shouldn't emplace_hint also return std::pair<iterator, bool> ?

[Ion Gaztañaga]

No, the standard interface for std::map/set::emplace_hint does not have it, just like insert with hint returns iterator.
