Yes, and this is a feature of the language that adds unnecessary
complexity.  You shouldn't be trying to duplicate it - you should be
trying to get rid of it.

You don't need singleton tasks, or protected objects, or arrays, because
you can use existing mechanism to do the job (ie declare a type, and
then declare one instance of the type).
