Make #[derive(Anything)] into sugar for #[derive_Anything] This is a hack, but I don't think we can do much better as long as `derive` is running at the syntax expansion phase. If the custom_derive feature gate is enabled, this works with user-defined traits and syntax extensions. Without the gate, you can't use e.g. #[derive_Clone] directly, so this does not change the stable language. This commit also cleans up the deriving code somewhat, and forbids some previously-meaningless attribute syntax. For this reason it's technically a [breaking-change] 2015-03-06 21:15:54 +00:00			`#[derive(Send)]`
