Ooops, sorry, I got header constants and status code constants confused, folks. Please ignore me. ~~Are these now also in the IANA list? That list is the only one claimed...

Do you have a use case in mind for this? Could you share?

Do those types of yours suggest any particular ordering for the `Uri` component? What I'm (just a contributor) looking for is if there is a particularly natural ordering. For example,...

`Authority` currently does a case-insensitive host `PartialOrd` which is different then ordering the output of `to_string()`. That might suggest this ordering is more consistent than my original suggestion: ```rust (self.authority(),...

Some thoughts from an interested user: Given new requirement on extensions, a breaking change then? You would apply the same to `Response`? It sounds like you would `impl Clone where...

The private `http::error::ErrorKind` shouldn't be in your way, since `http::Error` has `is` and `get_ref` for read access, and implements `From` (if "percolate" includes creating them). However, I see that `http::uri::InvalidUri`...

As another improvement (beyond #233) add (as of 37dafed) a `Debug` implementation for `ChainDisplay` as well. **Formal rationale**: As `Fail` requires `Debug`, so should `ChainDisplay` be `Debug`. **Practical reasoning**: Users...

This seems very similar to #176, where a workaround is to manually implement `Fail` for `MyError.`

Ran into needing to use UFCS in example usage of #233 (and my #244). Thanks for the explanation! I hadn't figured out why that was necessary. In #244 I added...

The _failure_derive_ → _failure_ is only a dev. dependency. The other direction, _failure_ → _failure_derive_, should be more relevant. For _failure_ 0.1.5 it is as follows. Its been using this...
