And access types are already default initialized to null, protected type 
components are like record components, and there's nothing visible in a task 
that needs initialization.

It's not a perfect solution in that you can't change the default 
initialization of an access type nor of an array type with non-scalar 
components, but it ensures that it is possible to provide (or have one by 
definition) a real default initialization for every type.
