I'd say reight before opendir()

Which is equivalent to
my @files;
since my() has the side-effect of clearing the declared variable.
Except = (); will help avoid "uninitialized value" warnings no?
That would be a "no"
That is only for scalars which makes so much sense now :)
$ perl -mstrict -we 'my $files;print $files;' Use of uninitialized value in print at -e line 1. $ perl -mstrict -we 'my @files;print $_ for @files;' $ perl -mstrict -we 'my %files;print $_ for keys %files' $
No more my @this = (); or my %that = (); for me!
So scratch what I said, what Gunnar said is better.
my @files;
is what you want, as my @files = (); is basically pointless ;p
