Gregory's Server@Conan_Kudo @pinskia @scherzog @crazyeddie @lina In your case, aren't the Rust RFC enough, or does divergeance between when they where accepted and the real implementation too much?
And when you speak about squeezing out everything from the language feels like compiler work (which isn't an issue if there is a single blessed implementation) than application/library work, or do I miss something?
@robinm @pinskia @scherzog @crazyeddie @lina Sometimes the divergence is meaningful between RFC and implementation. And even with a single compiler implementation, squeezing everything out the language matters. Because if you don't know what is safe to squeeze, the assumption can be violated in an upcoming revision without any real warning. It's the equivalent of dealing with nightly/unstable rust features.
I'm also for having multiple compiler implementations, which is way harder with no spec.
