The compiler team's explanation
A loop keyword (break or continue) was used inside a closure but outside of any loop.
Erroneous code example:
let w = || { break; }; // error: `break` inside of a closurebreak and continue keywords can be used as normal inside closures as long as they are also contained within a loop. To halt the execution of a closure you should instead use a return statement. Example:
let w = || {
for _ in 0..10 {
break;
}
};
