Did you just recommend 
our $foo;
local $foo = 1;
foo();
local $foo = 2;
foo();
sub foo {
    print "foo: $foo\n";
}

over 
my $foo;
$foo = 1;
foo();
$foo = 2;
foo();
sub foo {
    print "foo: $foo\n";
}

Either way, sounds like an awfully complicated way of avoiding passing a parameter. 
foo(1);
foo(2);
sub foo {
    my ($foo) = @_;
    print "foo: $foo\n";
}
