In my own experience, it really helps clear up nasty if/else chains in certain ...

The actual early return is implemented in the my_for_each function using the ? operator, which returns from the containing function if called on a Break value. Note that we have to check the return value of my_for_each to "catch" the

- Which is more readable: early returns, or conditionals?If you've decided that early returns are no good, but it also becomes too difficult or unreasonably messy to implement the single-return approach, because of the difficulty of getting to the bottom of the function (without using GOTOs), that is a sure sign that the entire thing is inherently poorly structured and needs to be broken down further ...
