Would be nice to have some and none like ok and err

[stevenj]

It would be cool to have equivalents to ok and err for some and none results.

So like this:

/// Logs `Some` results at the `info` level and `None` results at the `error` level.
#[logcall(some = "info", none = "error")]
fn divide(a: i32, b: i32) -> Option<i32> {
    if b == 0 {
        None
    } else {
        Some(a / b)
    }
}

And conversely, if only some is specified, it would not log on None or vice versa.

Good idea!
