If you are limited to one statement you could still do something along the lines of the following (no particular language):

  foreach ( $item in $list )
  {
    if ( 1 == some_function( $item ) )
    {
      continue;
    }
    else
    if ( 2 == some_function( $item ) )
    {
      break;
    }
    else
    {
      another_function( $item );
    }
  }

But I would immediately concede that it is starting to miss the entire point of why it was enforced in the first place...
