Re: [boost] [iterator] could non-small predicates/functors be stored as boost::optional<T> to avoid double construction?

Hi,

The headline pretty much says it all. Take transform iterator. When the predicate is not trivial, we also have a redundant construction of the object in the end iterator. Maybe that could be removed?

best regards

I guess that would be restricted to forward iterators.
