Mozilla Releases Rust 0.1

MrSeb writes "After more than five years in the pipeline, Mozilla Labs and the Rust community have released the first alpha of the Rust programming language compiler. The Rust language emphasizes concurrency and memory safety, and — if everything goes to plan — is ultimately being groomed to replace C++ as Mozilla's compiled language of choice, with Firefox (or parts of it) eventually being re-written in Rust."

No null pionters

From the article: "null pointers are not allowed". So what better type is there to represent what amounts to a tagged union [wikipedia.org] between a reference to an object and a value representing the lack of an object?

Wonderful!

Yet another solution in search of a problem.

Since this comes from the people who have identified a problem in a codebase they own that this is intended to address, I don't think that that's the case. It may not be a problem you have, and it may not be the solution you'd prefer in their place, but that's not the same thing as it being a solution in search of a problem.
