Also, more readable. Personally, I think it's sad that Rust (along other systems-oriented languages like D and Go) haven't taken more of the syntax from Python, which I find to be superior to the world of curly braces.
Agreed. Especially since Rust uses a lot of different sigils already (@ , ~, &, ::, <>, || for closures...). Using and/or, hopefully along with significant whitespace would reduce the visual clutter.
