Unexpected deparse output

When I run

~$ perl -MO=Deparse -e '
  use constant foo => 0;
  if ( (int(rand(2))+1) % 2 ) {
    warn "foo"
  }
  elsif ( foo ) {
    warn "bar"
  }
'

I get the output

use constant ('foo', 0);
if ((int(rand 2) + 1) % 2) {
     warn 'foo';
}
else {
     '???';
}
-e syntax OK


I would have expected the elsif to disappear entirely. Instead it is 
converted to this weird empty-else. Is the SCOPE op still there or is 
this just Deparse being silly?

Thanks!
