That won’t allow extracting a value from the optional though, will it? i.e. I can’t do this something along the lines of:

    if !matches!(val, Some(let x))

Indeed not, so it's not a full replacement. I'm not entirely sure that I like the idea of an "if let" variant creating bindings that escape the visual block, but I'd probably get over it.
