I agree, but we should leave this as a fallback case, albeit legitimate and 
not too difficult to justify. Here are a couple justifications:

- allocating memory (violates noexcept)
- retaining unknown quantities of memory (in the case of the assignment op)
- complex or slow code
- pessimises code elsewhere
