Putting a 'null' value in every type is also a popular language feature, but it's a bad one and Rust deliberately does something different, for safety. Argument by feature popularity doesn't mean much in a world where most languages are just some new syntax for the same (often broken) concepts.
As for this specific case, I think allowing overloading += makes sense, but I don't feel strongly. keegan ----- Original Message ----- From: "Artem Egorkine" <[email protected]> To: "Masklinn" <[email protected]> Cc: [email protected] Sent: Friday, August 23, 2013 11:52:49 AM Subject: Re: [rust-dev] Augmented assignment Augmented assignments are not unique to python.
