As stated in the specification:

  [Local Variables] ...  Such assignments must precede the zero-th
  argument of the simple command or the opening left parenthesis of
  the subcommand.

This also follows from the grammar: A [local] may
only appear in a [prefix] and a [prefix] may only
appear before a TEXT.
