Yes. But I have to admit that it has only been CGI scripts run under
Apache::Registry and similar.
The point I was trying to make is that package variables and lexically
scoped variables behave differently in this respect. However, see
Brian's message in this thread. Even if I haven't seen file scoped
lexicals retain their values, I trust that Brian knows what he is
talking about.
