For me, a non-toy project is a project that runs in production, where I can build my business on.

I know there are various pointer type prefixes in Rust (@foo, ~foo, &foo, *foo), 'foo for lifetimes and $foo for macro arguments, but WTH is +foo? https://github.com/mozilla/rust/blob/master/src/librustc/mid...

I haven't seen this in the documentation.

> Also, is anyone using Rust in non-toy projects?

Since it's not production ready yet: no
