Comment on Rust 0.4 call for testingparentComments−masklinn13yEven more functional-ish features: most block-based constructs are actually parse transforms on top of HoFs. For instance for 5.times { // code } desugars to: // |args*| { stmt* } is the Rust block syntax times(5, || { // code true // explicit order to continue })−asdfaoeu13yI somewhat wish they had used something like the ruby style for this to allow chaining of the blocks e.g. 5.times{|x| x}.select{|x| x < 3}.collect{|x| x + 2} Edit: Ok ignore that it seems they do have that (https://mail.mozilla.org/pipermail/rust-dev/2012-July/002000...) not sure of the difference, maybe just a result of the fast development.
