<span class="caption">Listing 18-9: Using `if let` and a block with refutable
patterns instead of `let`</span>

We’ve given the code an out! This code is perfectly valid, although it means we
cannot use an irrefutable pattern without receiving a warning. If we give `if
let` a pattern that will always match, such as `x`, as shown in Listing 18-10,

if we give `if let` an irrefutable pattern (a pattern that will always
