In the context of this discussion it is. We are talking about about
automatic cleanup
and whether it should happen immediatly after a name is no longer
available. or wait
until the object is garbage collected. The fact that I used a del for
illustrating the
possible problems is just a detail.

That other languages may have different semantics with the del statement
is irrelevant.
