That was my initial reaction, but the documentation suggests rather
strongly that *all* effects of b() are undone:
The `goto-&NAME' form is highly magical, and substitutes
a call to the named subroutine for the currently running
subroutine. This is used by `AUTOLOAD' subroutines that
wish to load another subroutine and then pretend that
the other subroutine had been called in the first place
(except that any modifications to `@_' in the current
subroutine are propagated to the other subroutine.)
