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.
