Actually, the person getting the error is using a Perl less than
5.6.  Since Perl 5.6, qw() becomes a (...) list at compile-time, so saying

  for qw( a b c ) {
    ...
  }

is valid.  Beforehand, qw() became a split() at compile-time, and thus

  for qw( a b c ) {
    ...
  }

is a syntax error that must be written as

  for (qw( a b c )) {
    ...
  }
