public @interface UnsupportedOperation
This is similar to the @NotYetImplemented annotation. The difference is only
the semantic: "@UnsupportedOperation" means, it is not supported yet and the
annotated method will probably also not supported in the future.
"@NotYetImplemented" means, that the method is not yet implemented but will
be available in the (near) future.
In PatternTesting Samples (patterntesting.sample.Fraction) you'll find an
example you to use it.
