Re: Rust front-end patches v4

We've also added one more commit, which only affects files inside the 
Rust front-end folder. This commit adds an experimental flag, which 
blocks the compilation of Rust code when not used. We hope this helps 
indicate to users that the compiler is not yet ready, but can still be 
experimented with :)

We plan on removing that flag as soon as possible, but in the meantime, 
we think it will help not creating divide within the Rust ecosystem, as 
well as not waste Rust crate maintainers' time.

Thanks again,

Arthur
