Niall, what does result represent?

Same as expected. It's legal to return that failure occurred, but no information as to why. I see that as being possibly useful. What's far more interesting is result. Yes expected is also legal too. Where things get mind bendy is that v2 result can return a T with additional info E, so you can quite legitimately have a result with both .has_value() and .has_error() returning true. I agree before you say it that that is daft. But I see no good reason to not support it other than "that is daft". And besides, outcome looks much more useful, and that would have a result internally, so there is a real actual use case for result.
