Error for visitors returning a moveable-but-not-copyable object

Reported by: Raffael Casagrande <raffael@…> Owned by: ebf
Milestone: To Be Determined Component: variant
Version: Boost 1.55.0 Severity: Problem
Keywords: rvalue, visitor Cc:

Description

I noticed that there is an error in boost::variant if one uses the visitor pattern and if the return type of the visitor does not posess a copy constructor but instead a move constructor. I've attached a small sample script that shows this behaviour.
