Description
Right now, if I assign @Unique to multiple properties, it will check each property and throw if just one matches.
But is there a way to group these together?
For example:
@Unique String firstName
@Unique String lastName
Currently:
put(new Name("James", "Hunt")) -> saved
put(new Name("James", "Lee")) -> UniqueViolationException
Expected:
put(new Name("James", "Hunt")) -> saved
put(new Name("James", "Lee")) -> saved

Research direction
Start by reviewing how @Unique is applied and how put(...) enforces uniqueness. Compare the current per-property behavior with the requested combined constraint using the Name examples; done means records sharing one property can be saved when the combined values are unique.
