[boost] [Phoenix-3] Is Actor assignable?

Hi, In Phoenix 3, is Actor assignable? This is necessary for filter_iterator/transform_iterator with Phoenix to be "neat" iterators. (Unfortunately, Actor is not assignable in Phoenix 2.) P.S. After writing this mail, I found this comment (What a coincidence ;-) #4853 (Actor is never assignable regardless of the template parameter) https://svn.boost.org/trac/boost/ticket/4853#comment:2 Comment (by theller): This is fixed in phoenix V3 So the answer to this question is YES. Thank you for great work, Thomas! Regards, Michel
