FP `expected i32, found ({unknown},)`, match on const, pattern

[matthiaskrgr]

fn main() {
    const PAT: u128 = 1;

    match 0 {
        (.. PAT) => {}
        _ => {}
    }
}

this compiles with rustc but rust-analyzer diagnostics . shows errors

at crate ra, file /tmp/ra/src/main.rs: Error RustcHardError("E0308") from LineCol { line: 4, col: 8 } to LineCol { line: 4, col: 16 }: expected i32, found ({unknown},)
