[Python-Dev] Python 3.x and bytes (original) (raw)

Here's another thought, that perhaps is not backwards-incompatible...

somevar[3] == b'd' At some point, the bytes class' eq will be called -- is there a reason why we cannot have 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?

Immutable objects that compare equal should hash equal; so we would also have to change the hashing of byte strings. Not sure whether that, in turn, has undesirable consequences.

In addition, equality should be transitive, so b'A' == 65.0.
