Thanks for the PR! This looks like an improvement to me, but I want to give @steveklabnik a chance to weigh in.

Specifically, with coerce as before, I interpreted it to mean that the underlying String was modified by as_slice() which was puzzling.

We haven't made a formal decision to use this 'view' terminology, but I do like it. I am neutral to mildly positive about this, so if @aturon likes it, r=me

I don't get how r=me is supposed to work. I could just r=me at aturon or steveklabnik or alexcrichton and bors would automatically merge without their explicit approval (I know how it's supposed to be written but am not trying to write it properly here)? Isn't that just bypassing the review process?

@Mdiner It's just an informal way of telling other reviewers that you're personally happy with the PR. Someone with reviewing rights still has to sign off.

(bors will only pay attention to r+ and r=somereviewer comments on the commit from people with reviewing rights.)

@steveklabnik Yeah, we should think more broadly about this terminology -- might be worth raising at the next weekly meeting. Want me to add to the agenda?

In any case, I'm happy to land this for now.

Okay. Thanks for clarification

@aturon sounds great, yeah. I'll come prepared :)
