Implicit class providing

methods.Implicit class providing
requiring
methods. This class is based onPredef.ensuring
in the Scala standard library. The difference is that this class's methods throwIllegalArgumentException
s rather thanAssertionError
s.An example adapted from

Create a comparator which will efficiently use
System.identityHashCode
, unless that happens to be the same for two non-equals objects, in which case the supplied “real” comparator is used; the comparator must be consistent with equals, otherwise it would not be an enhancement over the identityHashCode. - final def isInstanceOf[T0]: Boolean
