So are you saying that, in general, anonymous functions should not be used as

If its anything like in Java, (once the calling method returned) the
anonymous function would only be referenced by the event dispatcher and so
(assuming weak references are not used) would only be garbage
For me, the question is: If I use someObj in the same way as my example above
(i.e. assigning it to a local variable), when will someObj get garbage
collected?
Is it (potentially) when the result/fault event is dispatched or could it be
earlier?

Problem solved by removing the Bindable tag from the overriding method.
Shouldnt the compiler spot this?

Unfortunately, in my scenario, isAllowed() is not set in this kind of way -
its more of a calculation based on various vars elsewhere (some
