调研方向
The issue names union, intersect, and difference, and points to #91 and #56 for prior decisions and behavior. Read those discussions and the existing implementations and tests for these functions to understand their current semantics and the proposed Ord default. Done means the intended complexity and duplicate behavior are agreed on and covered by tests; the long discussion and prior pull request show this work may need maintainer direction.

描述
We already made nub use Ord by default in #91, but there are a few other unnecessarily quadratic functions in this library still which probably deserve the same treatment. I think these are union, intersect, and difference.
As well as being quadratic, union and difference have a strange-seeming behaviour where duplicates are only preserved in the first argument:
union [0, 0] [1, 1] == [0, 0, 1]
See #56 for more info. We ought to be careful about changing this behaviour but I think we should consider it, since I think it’s very likely to trip people up and we will be making breaking changes to these functions anyway if we do this.
