I'm a little confused by the response. It's not the dynamic-scoping-like behaviour that's the problem— 
my $x = 1;
my $f = sub { $x };
{
    $x = 2;
    print $f->(), "\n"; # => 2
}

works as desired. (I'm sure that “dynamic scoping” isn't the right term for that, but I didn't know a better.) The real difficulty (for me, anyway) is making a change in an inner scope to a lexical variable in an outer scope in such a way that the change will ‘revert’ outside that scope.
