If Rust had return type inference, it would be close to my ideal language

fite me
Me in Ruby: These two lines would be way clearer if I pull it into a method. Me in Rust: These two lines would be way clearer if I pull it into a function. Oh shit but the type is a pain to write... Oh right and lifetimes... Fuck it I'll just leave it.

Also me in Rust: Oh cool I can just return `impl Iterator` here! Oh but wait I also need it to be DoubleEndedIterator and ExactSizeIterator and Send and Sync and Copy Look I don't care if I couple to the exact type here do I really have to write this shit?

Also me in Rust: To ever abstract over Diesel queries you will have to at absolute minimum write: The SQL type of the select clause, the entire from clause, and the entire group by clause -- Always in cases where you don't care about coupling. Will never be concise w/o -> _

That's one bit of embarrassment in rust I'm not proud of. Impl Trait stabilizing will help much more that the tools we have today: leak concrete type or open your wallet and pay for a cosy box::new
