The three operators break, continue, and return (collectively ExitExpr) are all very simple syntactic sugar; they exist solely so that writing break instead of break() does not surprisingly do nothing (as it would if break, continue, and return were just conventional names for functions).
break break expr
expands to
__break() __break(expr)
and correspondingly for continue and return.
