I hadn't noticed that HQL projections would do that.
It seems useful indeed, but also quite irregular.. I'm not too
convinced, I guess I'd be happier if we could express the difference
on the method signature's return type.
I tend to agree that we should conform to the list() contract, but
this is unlikely to be an welcome change for existing users.
If you all agree it's an improvement, I'd schedule such an issue for 6?
