Replace otry! macro with ?

[maxbla]

lib.rs defines the otry! macro like this:

// Like `std::try!` for Option<T>, unwrap the value or early-return None.
// Since Rust 1.22 this can be replaced by the `?` operator.
macro_rules! otry {
    ($expr:expr) => {
        match $expr {
            Some(val) => val,
            None => return None,
        }
    };
}

Is this project trying to maintain backwards compatibility to before 1.22? Is there some other reason not to replace every instance of otry! with ? ?

It appears as if the otry! macro is used only a handful of times, so it could be fairly easily replaced.

Yes, this library maintain compatibility with Rust 1.15+

Do you mind me asking why?

[hauleth]

No, I am telling you that backwards compatibility will stay, so you need to use otry! in #42.

I prefer to maintain compatibility as much as possible. While ? for Option is certainly pleasant, it's not a big deal to just use otry!.
