Closer, but they're still not the same. This code works, 

sub f { &g; print @_; } sub g { $_[0] .= "o, w"; push @_, "orld\n"; } 
+f($x = "hell");

but if you change it like this, it breaks: 
sub f { g(@_); print @_; } sub g { $_[0] .= "o, w"; push @_, "orld\n";
+ } f($x
= "hell");

    Oh ok. That's even more evil than I would have normally thought. So &do_nothing; is like @_=do_nothing(@_) except that it doesn't make copies like would happen in that snippet.
