+SYNOPSIS
+    p -> X
+
+TYPES
+    p		pointer to an lvalue
+    X		identifier
+
+    return	lvalue
+
+DESCRIPTION
+    p->X returns the same as (*p).X.  Thus the current value of *p is
+    to be an object of a type for which X identifies one element.
+    p->X then returns the lvalue corresponding to that element of of the
+    value of *p.
+
+    The expression *p.X will cause a runtime error since this is
+    interpreted as *(p.X) in which p is expected to be an object of
+    an appropriate type.
+
+    Spaces or tabs on either side of -> are optional.
+
+EXAMPLES
+    > obj pair {one, two}
+    > obj pair A, B
+    > p = &A
+    > p->one = 1; p->two = 2
+    > A
+	    obj pair {1, 2}
+
+    > A->two = &B
+    > p->two->one = 3; p->two->two = 4
+
+    > *p->ptwo
+	    obj pair {3, 4}
+
+    > B = {5,6}
+    > *p->two
+	    obj pair {5, 6}
