/**
 * {@code Executable} is a functional interface that can be used to
 * implement any generic block of code that potentially throws a
 * {@link Throwable}.
 *
 * <p>The {@code Executable} interface is similar to {@link java.lang.Runnable},
 * except that an {@code Executable} can throw any kind of exception.
 *
 * <h2>Rationale for throwing {@code Throwable} instead of {@code Exception}</h2>
 *
 * <p>Although Java applications typically throw exceptions that are instances
 * of {@link java.lang.Exception}, {@link java.lang.RuntimeException},
 * {@link java.lang.Error}, or {@link java.lang.AssertionError} (in testing
 * scenarios), there may be use cases where an {@code Executable} needs to
 * explicitly throw a {@code Throwable}. In order to support such specialized
 * use cases, {@link #execute()} is declared to throw {@code Throwable}.
