By default it would work exactly as it does now.
By default, the engine creates stacks with their destroyStack property
set to false.
The destroyStack property is used to govern whether a stack remains in
memory when using "go" or "open", but it not honored when a property
within a stack is accessed.
By honoring the destroyStack property consistently, accessing properties
of stacks which have this set to true would cause the engine to read the
file, obtain the data, dispose of the copy of the stack in memory, and
return the value requested.
