1) a check to see if the bytes instance is length 1 2) a check to see if i) the other object is an int, and 2) 0 <= otherobj < 256 3) if 1 and 2, make the comparison instead of returning NotImplemented?

It might seem convenient, but I'd worry that it would lead to even more confusion in other ways. If someone sees that

some_var[3] == b'd'

is true, and that

some_var[3] == 100

is also true, they might expect to be able to do things like

n = b'd' + 1

and get 101... or maybe b'e'...
