I basically want to validate composite unique constraints

[Joris PZ]

[Joris PZ]

Well that would get you the unique values at least

[Bernhard]

and then I suppose compare the size

[Joris PZ]

Yes, that would work

[Joris PZ]

Would be nicer if it would short-circuit on the first non-unique item somehow, but I don't think there's a standard function for that

[Bernhard]

or duplicatesBy() 🙂
