A loop with at most one iteration is equivalent to the use of an `+if+` statement to conditionally execute one piece of code. If the initial intention of the author was really to conditionally execute one piece of code, an `+if+` statement should be used instead. If that was not the initial intention of the author, the body of the loop should be fixed to use the nested `+return+`, `+break+` or `+throw+` statements in a more appropriate way.
