A Java 8 class for when you just don't give a fuck about that checked exception

Nonchalantly.java

public interface Nonchalantly<T> {
    static <T, E extends Throwable> T invoke(Nonchalantly<T> f) throws E {
        try {
            return f.run();
        } catch (Throwable e) {
            throw (E) e;
        }
    }
    T run() throws Throwable;
    
    // USAGE
    // BeanInfo beanInfo = Nonchalantly.invoke(() -> Introspector.getBeanInfo(iface));
}

Clean and simple. Well done!
