Quantum does have a garbage collector. It works purely (and simply!) by reference
count.
Stream's are automatically closed and
Window's
are automatically destroyed when garbage collected. If you want to help the
Microsoft Windows operating system recover resources as soon as possible, you can
call
Fclose
and
DestroyWindow. It is possible to create "circular expressions" in Quantum. The Quantum
garbage collector cannot garbage collect these expressions until you break their circular
links. If you wonder what this fuss is about, evaluate
(Setq x [1 2]),
(Setq (Elt x 1) x)
in a Quantum Interpreter window. Remember the "stop button" on your Quantum
Interpreter window's toolbar. You can survive quite readily without circular
expressions even in your biggest Quantum megaprojects. |
