As an initial solution - I think that would work.
you may want to think about
http://perl.plover.com/FAQs/Namespaces.html
and that in the longer run having a clean API for your subs
that do not rely upon global side effects will be simpler to
maintain... I concede that there are a lot of times when one
needs to have functions that cause a global side effect - such
as signal handlers
my $run_flag = 1;
$SIG{HUP} = sub { $run_flag = 0};
while($run_flag) {
# do our main loop
}
Which I think is one of the rules that I general use about
deciding if a given function needs/can/should_be moved into
a perl module...
