It's precisely the structure of

package Fi;
#
sub two {
    say __PACKAGE__.q{::two};
    };
{ package Foo;
    #
    sub three {
        say __PACKAGE__.q{::three};
        };
    }; # End of package Foo!
sub four {
    say __PACKAGE__.q{:four};
    };

that messes up the sequential token scan! Both "two" and "four" belong to package "Fi". What is needed is traversing the document as a tree. (perldoc says " package NAMESPACE VERSION BLOCK").
