4425,qi::action ignores phoenix actor return value,anonymous,Joel de Guzman,"Hello,

this is not really a feature request but rather a design issue: It seems to me there is a discrepancy between the behavior of phoenix actors in comparison to functors called from qi actions.
In a functor, you can fail an otherwise successful parser by changing the ""pass"" argument. Intuitively, I would have thought that a phoenix actor such as
eps [phoenix::val(true) == phoenix::val(false)]
should also fail the parser.
However, action_dispatch ignores the return value from the actor and returns the pass argument, which the phoenix actor does not modify.
I'm not that well-versed in the insides of phoenix, but I can imagine that the actors know nothing about the pass argument. Should it not rather be action_dispatch, which in that case should perhaps AND the actor return value with the pass argument, so as to catch such cases?

Just a thought from an otherwise contended spirit user:-)",Feature Requests,closed,Boost 1.44.0,spirit,Boost 1.44.0,Optimization,wontfix,,
