That's an example of a tuple containing a recursive structure; there's still no way, starting at t, to get back to t.

[Barry]

Except, of course, at the C level.

I'm unclear on your meaning. In the specific example, you couldn't get from t to t period.

Do we care about that?

It may depend on what you really meant . If you're talking about creating recursive tuples via mutation in C, where tuples are the only container type involved, then 2.2.2 and 2.1.3 are broken now (they may blow the stack while comparing such beasts).
