I actually completely misunderstood your comments to bug #4782, and
thought you wanted to have some automatic way to evaluate the
complexity of a constructor.
And this was the more conservative counter proposal that would give you
more control, but still allowed for some automatism :-)

That's indeed the solution I would prefer as well.
