not necessarily, but there are lots of issues involved when doing high-performance XML stuff, and I'm not sure views would help quite as much as one might think.

(writing and tuning cET was a great way to learn that not everything that you think you know about C performance applies to C code running inside the Python interpreter...)

and also based on the cET (and NFS) experiences, it wouldn't surprise me if a naive 32-bit text string implementation will, on average, slow things down more than any string view implementation can speed things up again...

(in other words, I'm convinced that we need a polymorphic string type. I'm not so sure we need views, but if we have the former, we can use that mechanism to support the latter)
