Use a my declaration before using a var in your subs, then you'll "avoid closures".

    Will this avoid closure?

    my $test = "a";

    sub test {
    my $temp = $test;
    }

    Will $temp avoid closure?

      well if you meant $temp instead of $test ... YES!

      my $temp = "a";

sub test {
   my $temp = $test;
}

      update

      Basically does a my variable (aka lexical) belong to the surrounding '{ BLOCK }'.

      A sub's (or an if's) body is a { BLOCK } and the file itself (i.e w/o surrounding curlies) is practically the top-level block.
