Maybe what you are after is somewhat like this:

use strict;

{ # just a block
    my $test; # the lexical one
    sub foo {
        print "In foo: \$test=$test\n";
        $test = "Hello world";
        print "In foo: \$test=$test\n";
    }
    sub bar {
        print "In bar \$test=$test\n";
    }
}

my $test; # the global one

print "Global \$test=$test\n";

foo();
print "Global \$test=$test\n";
bar();
print "Global \$test=$test\n";

The two functions are defined in a block and therefore share the lexical (please do not use the term local in Perl) variables declared within that block ABOVE the functions.
