This

 sub FH :lvalue  { my $fh }

should do.

But I don't have the time to test it in all edge cases.

    You are correct about needing the :lvalue attribute, but if I understand correctly, my will create a new scalar every time FH is called.

    Another alternative could be: { my $fh; sub FH :lvalue { $fh } }, using the closure to capture a single instance of the lexical. TIMTOWTDI really works!

      you are right of course, a closure was my initial idea, dunno why I lost it here.

      FWIW state might be an alternative
