end of the array. Therfore, runtime array can be implemented as a zero length
array type.

Also, note that if the bitwidth of `offset` or `count` is greater than the

defined behaviour with `offset` and `count` being less than the size of
`base`. It creates a natural upper bound on what values `offset` and `count`
can take, which is 64. This can be expressed in less than 8 bits.
