I tend to agree. I think we should just live with the fact that not
every conceivable use case will be covered, at least initially. Then,
if an appreciable demand for even more flexibility emerges, we can
revisit this. We already have a syntax that is significantly more
flexible than the equivalent feature in any other system. Let's not
lose sight of that.
