source: src/Concurrency/Actors.cpp@ 4d5c5b6a

Last change on this file since 4d5c5b6a was ab94c37, checked in by Andrew Beach <ajbeach@…>, 8 months ago

Change in actor ?|? function generation. It looks accessive (and in a sense it is) but this makes it constent with the general return pattern that makes sure the assignment is called. This removes a lot of warnings, but nodebug builds of the actor still fail because of another warning.
