Before the horse is totally dead... (maybe it already is), a couple comments:

IF someone is proposing a nice lib for "low level data buffer manipulation", then yes, putting frombuffer() in there would be a fine idea. But if there is no such proposal on the table, then I think adding a frombuffer method to the bytes object is a small improvement that we can do now. https://blog.sentry.io/2016/10/19/fixing-python-performance-with-rust.html pretty cool -- I guess I should take a look at Rust...
