public Type childExpectedType(Expr child,
AscriptionVisitor av)
Nodethis.
The expected type is determined by the context in that the child occurs
(e.g., for x = e, the expected type of e is
the declared type of x.
The expected type should impose the least constraints on the child's
type that are allowed by the parent node.
