public Type childExpectedType(Expr child, AscriptionVisitor av)
Node
this
.
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.
