Your view of "garbage" is too limited.
In the context of "garbage collection", isn't the view rather well
defined? I wonder what yours is. My view is that it's a resource which
can be used and later returned to availability, but has somehow been
misplaced before being returned. Nothing is actively using it, or *can*
actively use it, because the way to use it has been lost.
I suppose one can intentionally create something like garbage in Tcl by
discarding the result of a command like [open] or [image create] (though
it's probably still theoretically possible to recover such handles with
suitable introspection). But that strikes me as a contrived example.
