CoerceToDomain

CoerceToDomain represents the operation of coercing a value to a domain type. At runtime (and not before) the precise set of constraints to be checked will be determined. If the value passes, it is returned as the result; if not, an error is raised. Note that this is equivalent to RelabelType in the scenario where no constraints are applied.
