|Subject:||child functions (via Wheel::Run) could return values|
While constantly forking/exiting functions has a certain amount of overhead beyond simply forking a persistent transaction processor, it does present a seductive level of simplicity. Provide a Wheel::Run flag/mode that lets child functions (Program => \&code) return values. The child and wheel would agree to use Filter::Reference to pass back whatever, possibly including the value with CloseEvent. Suggested by "trhtgtfr" on efnet #poe.
