Accessing stacks without opening

Hi Marty,

When you reference a stack that is not open, it is brought into memory. 
Even this will do it:

     -- set 'it' to true or false
     get (there is a stack "abc") -- looks in the default folder for the 
stack

Or you can reference the stack by its filename.

When a stack file is brought into memory this way, none of the normal 
preOpen / open messages are sent to it or its parts. AND visible stacks 
are not shown. You can definitely use this to your advantage in certain 
cases! It is not bad form. The important thing is that you know what's 
happening.
