Whoops! I meant to paste in the URL, but forgot - https://github.com/rust-lang/rfcs/pull/65 Sorry about that.
We used to have anonymous structs and they were removed (before my time, so I can't tell you the reasons, sorry), so it is very unlikely we'll get them back. If we did want to, then they could be added backwards compatibly, so they could be considered post-1.0.
