我研究了Y Combinator(使用c#5.0)并且在这种方法时非常惊讶:

public static  Func<T1, Func<T2, TOut>> Curry<T1, T2, TOut> ( this Func<T1, T2, TOut> f)
{
    return a => b => f(a, b);
}

...由编译器翻译成:

public static Func<T1, Func<T2, TOut>> Curry<T1, T2, TOut>(this Func<T1, T2, TOut> f)
        {
            first<T1, T2, TOut> local = new first<T1, T2, TOut>();
            local.function = f;
            return new Func<T1, Func<T2, TOut>>(local.Curry);
        }
    private sealed class first<T1, T2, TOut>
    {
        private sealed class second
        {
            public first<T1, T2, TOut> ancestor;
            public T1 firstParameter;
            public TOut Curry(T2 …

最近我写了一些树,想尝试不安全的代码.最后我做的都没有不安全但是在这段代码中找到了一些模糊(对我而言)的地方(对于更短的代码,我删除所有逻辑,所以所有代码看起来都毫无意义):

public static void Main() {
        EqClass a = new EqClass();
        a.AddElement(2, new record(3)); // *place1*
                    ...
            }
    unsafe struct node {
        public node* next;
        public record Value;
        public node(record value) {
            this = new node();
            this.Value = value;
        }
    }
    struct record {
        public int a;
        public record(int a) {
            this.a = a;
        }
    }
    unsafe class EqClass {
        node*[] last = new node*[3];
        public void AddElement(int classIndex, record element) {
            node a = new node(element);
            node* newNode = …
