Hi, in C++ I can use smart pointers to wrap raw pointers with custom deleter to automatically manage C resources. Is there anything like this in D?

1) Structs provide RAII:

struct S
{
    // ...

    ~this() {
        // cleanup
    }
}

2) catch and finally clauses can be used

3) scope(failure), scope(exit), and scope(success):

{
    auto r = allocateSomeResource();
    scope(exit) deallocateSomeResource(r);

    // ...
}
