Did you know you could actually get the result you expected, just by replacing my with local? It changes the two lexicals into one global variable that temporarily changes value. 
local $foo = 1;
foo();
local $foo = 2;
sub foo {
    print "foo: $foo\n";
}

Of course, I did have to drop the "use strict;" to make it work, because local is not a variable declaration. You can still prepend "our $foo;" to add the actual declaration, and strict will no longer complain.
