/**
 * This functional interface allows to not catch an Exception in a
 * lambda expression : use it at your own risk, the exception
 * becomes unchecked.
 * It is recommended to use it only in a method that can throw the
 * Exception type that is unchecked. So the exception can be
 * checked when using the method.
