I'm trying to let programmers make the call here, which is why Virgil gives you both options. In causal hacking, anonymous tuples can be very useful. I find that very true in test code, where I have a tendency to throw more bells and whistles at it to get meat of the tests really short (so I can write a lot of them). Requiring elaborate ceremonies (such defining a bunch of tuple types for no good reason) is just a waste of time.
