Which errors would __getitem__ miss? At least type errors that don't coerce; are there other cases?

The issue with a deep copy of the whole dataset is that it's very expensive. It's probably better to have that rather than nothing, but it could have confusing performance effects given that people are often going to be mutating values to reduce copies.

These aren't strongly held views though. Any thoughts from others?
