extern crate "std" as other;
extern crate core;

fn main() {
    [0i32][];
}

$ rustc --version
rustc 1.0.0-dev (012e9643e 2015-02-08 16:47:12 +0000)

$ rustc foo.rs
foo.rs:8:5: 8:8 error: failed to resolve. Maybe a missing `extern crate std`?
foo.rs:8     [0i32][];
             ^~~
foo.rs:8:5: 8:13 error: `std::ops::RangeFull` does not name a structure
foo.rs:8     [0i32][];
             ^~~~~~~~
error: aborting due to 2 previous errors

The desugaring happens in the parser.

See also #20516. Was #21827.

Looks like this has been fixed on nightly.
