But Rust 1.0 can't compile Rust 1.1. And as others have noted, C99 is a standard and Rust lacks one.

  But Rust 1.0 can't compile Rust 1.1 That's an impossible standard to hold Rust to, did you mean it the other way around? A C89 compiler can't compile all of C99 either.

    But v1 of a C99 compiler can compile all of C99, and v2 of a C99 compiler can still compile all of C99.
