It has gotten a lot friendlier-looking in recent versions, thanks to the reduction in odd type-punctuation for lifetime description. It's more uniform now.
I don't understand the problem. Rust doesn't have # for comments, and I find `#[random]` easier to the eyes then `@random`. Or are we speaking about `@[random]`? Then again, I've never been one for micro-syntax-discussions.
That's not really a sensible association. A lot of work is done with those languages where shells are either not used at all, or are just a development tool (e.g. could be replaced by editor features). It seems rather strange to try to forcibly connect Python/Ruby/... and sh, rather than just grouping as languages that happen to share the # for comments. (Maybe they adopted it from shells originally, but the languages definitely stand on their own now.)
