New submission from Marcel Martin <python at marcelm.net>:

It would be great to be able to use peek() on BytesIO objects.

I have a function that gets passed a file-like object and uses peek() on it. This works for nearly all types of files relevant in my library, except BytesIO instances (which I use during testing), for which I need to add a small workaround using tell() and seek().
