Pattern matching on unsafe pointers doesn't work

[brson]

I've wanted it at least once.

@brson what do you envision for "working"? For example, the following compiles and runs:

fn main() {
    let x = 4096 as *u8;
    match x {
        _ => fail!("foo")
    }
}

Triage. I suspect this refers to match pointer { *value => ... }. You can match values of type &T with pattern &pat, but can't match values of type *T with pattern *pat at the moment. Indeed, *pat is an invalid pattern syntax now.

I'm pulling a massive triage effort to get us ready for 1.0. As part of this, I'm moving stuff that's wishlist-like to the RFCs repo, as that's where major new things should get discussed/prioritized.

This issue has been moved to the RFCs repo: rust-lang/rfcs#641
