I've long enjoyed structures like this, of some kind of enforced minimalism, in part because it's the opposite of my natural tendencies toward let's call it expansiveness (I count among my favorite writers Neal Stephenson and David Foster Wallace, neither of whom you'd exactly call terse), but also because there are flavors of expression that open up when you do so, ways in which the rhythm of a sentence might meander and flow along pathways that differ from what would be regarded as normal or typically desirable, and when you seek the maximum expansion within the constraint--that is to say, when you really embrace the constraint--then you discover within and through those erstwhile limitations some really delightful potential for fun, which might for example express itself as a sentence which is grammatically correct, clear in its meaning, and also goes on for a ridiculously long time.
