Corrected version of the above to avoid an unintended syntax change:

   statement ::= (simple_stmt
                   (NEWLINE | ";" [stmt_list] NEWLINE | local_namespace)
                  ) |
                 (compound_stmt [local_namespace])
   local_namespace ::= "with" ":" suite

(The original version incorrectly prohibited a trailing semi-colon for a single 
statement)

Cheers,
Nick.
