You don't know of any other languages that use `mod` to represent "module"? Say, perhaps, the one you just advocated for in another thread? And there are in fact issues with using x => y syntax for lambdas without a leading fun/fn keyword: let x = (this, is, a, really, long, thing ) => 10; - In that example it's not possible to tell if the leading ( is the start of a pattern for the sake of lambda, or a tuple. This happens with ES6 today as well (destructured record argument). It's not just a matter of human readability, it's a matter of building an efficient parser. - The (x : y) syntax for type annotations is not new or weird to many people. That's the syntax used by ML, OCaml, and JS (Flow). - We're likely going to swap some operators for string concat, so that it would be the more common ++ operator. - The rest of the observations are good and we should address them soon.
