REVISION SUMMARY
  - Disallow some illegal expressions.
  - Fix chained print expressions.
  
  This causes 10 first/follow conflicts, where I'm not sure how
  to solve them or if that would even be feasible to do. Example:
  
    <? print 1 || print 2 || print 3; ?>
  
  php-parser handles this correctly, but conceptually it wouldn't
  know if the second || belongs to the first booleanOrExpression or
  is a new booleanOrExpression below the assignmentExpression of the
  second print.
