I wrote a few hundred lines about bout a year or two ago and about 2k the last few months. It's definately gotten better and there's something in the works for most of the things I took issue with which is kind of nice but doesn't really help if you're not on nightly.

Specific pain points for me were: - the lack of traits for numeric primitives/types without pulling in the num crate - the difficulty working with floating point types - the inconsistent type annotations in fn signatures - the type annotations are a bit clunky no easy way to alias - and auto deref mechanics especially via match statement - having to fully specify a type in a match statement or use Self::Type - the use mechanism makes no sense - no optional/default arguments without macros leads to a lot of shimming/boilerplate - having to split operations because the borrow checker can't do partials or non lexical lifetimes - the clunky range syntax wich makes writing invertible/reversible functions really ugly and error prone due to lack of inclusive range and I really can't believe the committee decided to go ahead with ..= instead of ... It's really out of line compared to pretty much every other language is doing - doesn't seem like there's a good way to nicely format long lines

Overall I still really like the language but I really don't see it taking off until these issues are fixed because it makes it so hard to start up.

Cool, thanks. Some of these things are being fixed, some of them, not, or at least not any time soon. (FWIW, I agree with you regarding =. We'll see...) I could go through the exact details if you care, but I won't bore you with it otherwise. Thanks for the feedback; it's really helpful.
