Am I doing something wrong?


import core.memory;

     void main()
     {

         struct S
         {
             int x;
             this(this)  disable;
             ~this()  safe pure nothrow  nogc {}
         }

         S* p;

         // rvalue
         p = moveToGC(S(123));
         assert(p.x == 123);

         // lvalue
         auto lval = S(456);
         p = moveToGC(lval);
         assert(p.x == 456);
         assert(lval.x == 0);


     }

Please provide the error message(s) when asking questions like 
this. In this case:

```
onlineapp.d(15): Error: undefined identifier moveToGC
onlineapp.d(20): Error: undefined identifier moveToGC
```

Looks like moveToGC was added in 2.096:

https://github.com/dlang/druntime/commit/bf59d2dcc4eae068a37db169977eef3eb394cee6

Adding --version to the ldc command line at run.dlang.io shows 
it's running ldc 1.25.1, which is current with D 2.095.1.
