[Second review] SE-0453: Vector, a fixed size array

I might be more amenable to this argument if this thread hadn't already suggested a whole family of Array types that include non-resizable versions. Even if they weren't, the argument for resizability as the single, fundamental property of the thing we call 'array' hasn't been made. In fact, outside of Swift, that's generally not the case. The properties Becca outlines are (more) universal, as much as something can be across all programming languages.

Even if none of this were true, I think this is a rather strange notion of 'newcomers'. Newcomers don't usually start by trying to distill the general, undocumented properties of the types they use. They try to find the things they need, use them, then maybe remember what they were for next time. Anyone trying to form some sort of generalized notion of the properties of collection types in a language is likely already flexible to understand non resizable types with 'array' in the name.
