> Implement support for IN as a Boolean-valued expression, e..g.
> select col1 IN (1, 2, 3) from T;
> or
> select col1
> from T
> where NOT (col1 IN (1, 2, 3));
> This will also automatically add support for NOT IN because NOT IN is
> automatically transformed into NOT ( ... IN ... ) by the parser.
