* The template parameter provided to `FixedArray` for the number of inline elements is named `N`
* If left defaulted, which is recommended, `FixedArray` chooses the number of inline elements by itself
* The `inline_elements` static class member contains the actual number of inlinable elements
* Previously the docs referred to the template parameter as `inline_elements` instead of `N`.
