One Class Data Stack instance is associated with each job, and implements the programmer-visible evaluation stack.
There is no way to create instances of this class other than by creating new jobs: The class exists specifically to let the server efficiently distinguish job evalation stacks from other sorts of stacks, in support of debugging and security.
Class Data Stack adds the following properties to those of Class Plain:
$S.vector: The vector used to actually hold the stack contents. $S.length: The current number of occupied slots in the stack.
Note: For convenience, the $S properties are also available in the public (default) propdir.
