This is the normal contract on parameter and result types. Eiffel
contracts also include arbitrary boolean expressions, extending the
contracting idea far into the area of program semantics.
Just as a parameter type makes clear what sorts of parameters are
required, the preconditions make clear under what circumstances the
routine may be called and expected to return a correct result. The Eiffel
postconditions list what the routine guarantees to the caller in turn.
