@nikomatsakis Did you intend to mere this or were you waiting on something? |
|
Would a conversation about autoderef behavior in patterns be part of this? |
|
I personally see that as pretty orthogonal. |

There was a problem hiding this comment.
I think this note accurately captures the primary benefits of this: the compiler could avoid inference failures by considering the reference and non-reference possibilities without them being completely separate impls.
It might be worth mentioning something here about other tradeoffs. And in particular, we should consider whether there are circumstances where we might not want this behavior for a type, and whether people should be able to opt into or out of this behavior for a type.
