What are the advantages of saving the end as a pointer? Genuinely curious. Seems like a length allows the end pointer to be quickly calculated (data + len), while being more useful for comparisons, etc.

You can remove the first k elements of a view with data += k.

With the length you would need to do data += k; length -= k

Especially if you want to use it as safe iterator, you can do data++ in a loop

How would you safely free(data) afterwards? You'd need to keep an alloc'ed pointer somehow.
