The adverse effect here is that it increases complexity. That's especially problematic in `string`, which is probably the most complex class in the whole code base implementation-wise. I'm also not sure why use-after-destroys wouldn't be detected anymore, since the compiler now knows that the contents of the string aren't to be touched anymore.
