          But please do not go there.

          There is a bit more to this. As a result of this kludge, it is
illegal to have newlines at certain points in some statements. For
example:
                    return
                      <expression which I decided to put all on its own line>;
is not legal. It is not permitted to have a newline immediately after
"return".
