That's somewhat the whole purpose of weird-exprs.rs: Abuse rust's syntax to make an expression look like something different (ensuring that it'll always be parsed correctly). Similarly, fn closure_matching() does not in fact match on closures.

loop {
if! {
match! (
break! {
return! {

}
}
)

{}
}

{}
}
