URL to the section(s) of the book with this problem:
https://doc.rust-lang.org/book/ch19-02-refutability.html#listing-19-10
Description of the problem:
The lines above this listing describe that the Listing uses if let that should be giving a warning because they are putting an irrefutable pattern in, but the listing uses let.
Suggested fix:
listing 19-10 should be changed to
fn main() {
// ANCHOR: here
if let x = 5 else {
return;
};
// ANCHOR_END: here
}
