ComplexEventHandler class
An EventHandler that cannot be expressed as a SimpleEventHandler.
This might be a be a single method call with multiple arguments, or an argument other than the $event parameter. It may be an expression other than a method call. It may also be multiple statements that have been merged together.
In generated code, this requires a generated method to wrap the event handlers.
