boost::apply_visitor compilation failure when used with inlined lambda transfering unique_ptr ownership

Description

Hi,

I have a lambda that captures std::unique_ptr ownership by move on it's capture list and transfers is further.

When such lambda is inlined in boost::apply_visitor function it failes to compile. I think it's connected with boost::apply_visitor template deduction .

Wordaround is to create functor not and pass it to apply_visitor.

Minimal example reproducing problem with boost 1.65 is includded as attachment and also can be found here: ​http://coliru.stacked-crooked.com/a/955148fcc337290f

Compilation log is included as attachment.
