NodeOpsTypeSystem.
This method is called by the leave() method of the
visitor. The method should perform work that should be done
after visiting the children of the node. The method may return
this or a new copy of the node which will be
installed as a child of the node's parent.

public Type childExpectedType(Expr child,

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.
