Perhaps this has been considered already, but when I'm reading rust code "let mut" just seems to stick out all over the place. Why not add a "var" keyword that does the same thing? I think there are lots of good and bad reasons to do this or not do it, but I just wanted to propose the idea and see what other people are thinking.
`let` takes a pattern. `mut` is a modifier on variables in a pattern. It is reasonable to write `let (x, mut y) = ...`, `let (mut x, y) = ...`, `let (mut x, mut y) = ...`, and so forth.
Having a special "var" syntax would defeat this orthogonality. Patrick _______________________________________________ Rust-dev mailing list [email protected] https://mail.mozilla.org/listinfo/rust-dev
