4. Why separate exception() from result() for Future class? It does the same as result() but with different interface (return instead of raise). Doesn't this violate the rule "There should be one obvious way to do it"?

I expect that's a copy-and-paste error. exception() will return the exception if one occured. I don't see the typo. It is as Nick explained.

PEP 3156 says "exception(). Difference with PEP 3148: This has no timeout argument and does not wait; if the future is not yet done, it raises an exception." I assume it's not supposed to raise.
