[Python-Dev] TextIO seek and tell cookies

[Guido van Rossum]

Be careful though, comparing these to plain integers should probably
be allowed, and we also should make sure that things like
serialization via JSON or storing in an SQL database don't break. I
personally think it's one of those "learn not to touch the stove"
cases and there's limited value in making this API idiot proof.
