I'll comment in context to the example you gave for passing parameters to
Queue/Synchronize (a custom class with a suitable public method)
- no need to declare a special class that handles the call
- no need to allocate a class
- no need to call "Free"
And with anonymous functions:
- the functionality is defined where it is needed (inside the parameter
clause of Queue/Synchronize or in case of nested procedures at least inside
the same method)
