I like this. It seems similar to `if let Some(value) = option` in Rust, with `?` replacing the pattern matching and supporting multiple assignments. Rather than something like this: if let Some(a) = option_a; let Some(b) = a.option_b { ... } else { ... } you'd have something like this: if let b = option_a?.option_b? { ... } else { ... } (Pseudocode for both examples.)
