I've developed in a mixed object/functional style for years, and I
think a lot of other people do, too. You don't need language support
for this, though I expect it would be helpful. It makes concurrency
and distributed programming easier, and is important when you are
dealing with databases. Eric Evans calls this "Value Object" in his
book "Domain Driven Design".
