Just by the way...

Now, that's cool; OTOH we have lvalue-able subs, but what about them? 
$ perl -le 'my $u; sub u :lvalue {$u} print ref \u'

Huh, no, it's just a plain old SCALAR.

You didn't print a reference to the lvalue sub u(). If you had, you would have gotten CODE. 

$ perl -le 'my $u; sub u :lvalue {$u} print ref \&u'

You printed a reference to the return value of a call to u(). That's the same thing as a reference to $u itself.

$ perl -le 'my $u; sub u :lvalue {$u} print ref \u; print \u; print \$
+u'

Update: On second reading, I guess maybe I missed your point. Nevermind me. Move along.
