It does on my system:
#!/usr/local/bin/perl
use strict;
use warnings;
use DBI;
my $sth = DBI->connect();
while( my @dat = $sth->fecthrow) {
print "dat: ", join(",",@dat), "\n";
}
% perl -c esposito.pl
Global symbol "@dat" requires explicit package name at esposito.pl line 9.
Global symbol "@dat" requires explicit package name at esposito.pl line 10.
esposito.pl had compilation errors.
perl v5.10.1
