It's static and lexical to two subroutines.

And yes, localizing a var is a trick. Something that confuses most newcomers to Perl. Localizing a whole typeglob so that you could call the newly created closure as if it was an ordinary subroutine doubly so. If you insist on using local(), localize the $move_disk and define the _hanoi() as an ordinary subroutine accessing the package variable $move_disk.

BTW, what was the last time you actually generated a stack trace?
