It would be nice if Block and Series types could be the same underneath

Currently they are not the same type (and don't share the same iterator) because a const generic is used for the stride quantity on the Series.

A const generic cannot be filled in by an expression based on another generic at this time. In other words, for the Block, we can't say that it's just an alias of the Series with the stride filled in as the size_of::<T>().

We could:

• use a field.
• wait for const generics to allow this.
• just live with the separation forever.

Given the discussion on zulip, it seems this won't be possible for quite some time.
