Actually, according to the POSIX grammar, http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_10_02, the syntax for <for_clause> includes a <do_group>, which is 'do' <compound_list> 'done'; and the syntax of a compound list can end in a <separator_op> which is either '&' or ';'. Using BOTH '&' and ';' is the true syntax error, and the above example is not a workaround, but the correct syntax. - -- Life is short - so eat dessert first!
