'next' is not needed here.
Also the whole thing could be written as this simple but more efficient way,
sub matching
{
my @[EMAIL PROTECTED];
my $eval=join "||", map { "\$_[0]=~m/\$inits[$_]/o" } 0 .. $#inits;
my $ref=eval "sub { $eval }";
die "can't eval: $@" if $@;
return $ref;
}
my $match_ref=matching(@id_hits);
while(<$FILE>) {
print if $match_ref->($_);
}
Hope this helps.
