What's the problem? I don't see how struct/class can change there 
anything, it's a member field that is an array that we surely can expand.

Buffer is created with factory functions only. It's not like an AA that 
grows from an empty/null state. Empty buffer (.init) doesn't grow it's 
simply empty.
