Read the grammar (section 3.10.2).  The `for_clause' production requires
either `in wordlist' or nothing following the `for name linebreak'.  A
`wordlist' may not be empty.  There is no special case listed at the
beginning of the section that would make an empty wordlist acceptable to
the for statement.

The description in assumes that there is a non-empty list of
items following `in', as the grammar guarantees.
