Note, however, that there are cases where it is not actually necessary to
set an object variable to nothing. This happens automatically when the
variable goes out of scope. Also, simply setting an object variable to
nothing may NOT be all that is required to properly clean things up - think
of the need to .close an output file, for one obvious example.
