This does not address the main issue.  Anonymous functions cannot be
linked to an upgrade path, even if the source code is known.

For instance, the following code:

    function bar1() { return &foo(); }
    function bar2() { return &foo(); }

is upgraded to:

    function bar1() { return &foo(); }
    function bar2() { return &gnu(); }

An anonymous function exported by this object has no unambiguous
upgrade path.
