the doc says::

exec_stmt ::= "exec" or_expr ["in" expression ["," expression]]

imho it should read ::

exec_stmt ::= "exec" expression ["in" expression ["," expression]]
| "exec(" expression [ ", expression" [ ", expression" ]] ")"

That would be correct as a handwaving description, but it's wrong as a formal spec. The "or_expr" already includes the possibility of a tuple; there is no "exec(" token etc.
