heap

直接使用动态内存管理器的不安全接口，类似于 malloc、realloc 和 free。手动内存管理可以与垃圾收集并行使用，这非常方便，但是手动管理的块不能与垃圾收集的对象混合（即尝试分别对 GC 对象进行 heap.free 或将块强制转换为托管对象会中断，因为 有 GC 标头，而另一个则没有）。

¥An unsafe interface to use the dynamic memory manager directly, resembling malloc, realloc and free. Manual memory management can be used in parallel to garbage collection, which can be quite handy, but manually managed blocks cannot be mixed with garbage collected objects (i.e. trying to heap.free a GC object or casting a block to a managed object respectively would break since one has a GC header and the other does not).
