data.getbyte(index_or_slice_object) ? while it might not be... ideal... to create a sliceable live view object, we can have a method that accepts a slice, even if we have to create it manually (or at least make it convenient for those who wish to wrap a bytes object in their own type and blindly pass the first-non-self arg of a custom __getitem__ to the method). > The rationale for "Why not a live view?" is that an iterator is simple > to define and implement, while we know from experience with memoryview > and the various dict views that live views are a minefield for folks > defining new container types.
