Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @steveklabnik (or someone else) soon. If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. The way Github handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes. Please see the contribution instructions for more information. |

Thanks @lorenzb ! This looks fine to me, but I'd like @nikomatsakis to check it out too. |

…sakis My main sources of information are [RFC401](https://github.com/rust-lang/rfcs/blob/master/text/0401-coercions.md), the rust IRC channel, and a bunch of experiments to figure out what `rustc` currently supports. Note that the RFC calls for some coercion behaviour that is not implemented yet (see rust-lang#18469). The documentation in this PR mostly covers current behaviour of rust and doesn't document the future behaviour. I haven't written about receiver expression coercion. I would be happy to rewrite/adapt the PR according to feedback. r? @steveklabnik
