/**
 * This class provides utility functions, and classes for working with the {@code java.util.function} package, or more
 * generally, with Java 8 lambdas. More specifically, it attempts to address the fact that lambdas are supposed not to
 * throw Exceptions, at least not checked Exceptions, like instances of {@link Exception}. This enforces the use of
 * constructs like:
 *
 * <pre>{@code
 * Consumer<java.lang.reflect.Method> consumer = m -> {
 *     try {
 *         m.invoke(o, args);
 *     } catch (Throwable t) {
