Simple macro to simplify Option handling in Rust.
This is my answer to RFC 1303 issue.
Like other Crates you should use cargo-edit and then:
cargo add soma
This is equivalent to try! macro from libstd:
```rust
extern crate soma;
// …
let foo: Option
let bar: usize = try_some!(foo); // This will return with None if foo is
// None
// equivalent to:
//
// let bar: usize = match foo {
// Some(val) => val,
// None => return None,
// }
let baz: usize - try_some!(foo => return); // This will break execution if foo
// is None
// equivalent to
//
// let baz: usize = match foo {
// Some(val) => val,
// None => return,
// }
```
