Or, just add () to GUSI::AF_FILE.  Yesterday Randal Schwartz and Tom
Christiansen were arguning about this ... & circumvents prototypes and also
allows access to any subroutine name, like &if.  Tom thinks this is bad,
Randal thinks it is good.  I tend to go along with Tom on this.  Randal
contended that & is good for beginners who don't need prototypes anyway and
might mistakenly use a subroutine name that is reserved; but I think that
good programming practice begins as early as possible.

Back to your regularly scheduled sermon ...
