/**
 * @assertion A read of a field or variable which is marked as late which has
 * not yet been written to causes the initializer expression of the variable to
 * be evaluated to a value, assigned to the variable or field, and returned as
 * the value of the read.
 * ...
 * Evaluating the initializer expression may validly cause a write to the field
 * or variable, assuming that the field or variable is not final. In this case,
 * the variable assumes the written value. The final value of the initializer
 * expression overwrites any intermediate written values.
 *
 * @description Check that it is a compile error if initializing expression
 * writes an intermediate value to final field or variable
