Maybe the order for d[k] = v should also be reconsidered?

If so, it would be something like:

  1. Evaluate d
  2. Evaluate k
  3. Evaluate v
  4. Call d.setitem(k, v), via slots etc

In a vacuum, I don't have a problem with that. But I suspect that it'd break more code than the comprehensions changes do.
