destroy and @safe

[Antonio]

I'm using explicitly destroy!false(obj) for a "deterministic" 
resources release.

I replicate the c# "using" pattern, or the python "with" pattern 
with my own "use" template supposing object are RAII

i.e.:

```d
Item[] items = query("...").use( (Answer a) =>
   a.rangify.map!(rowToItem).array()
);

```

The problem:

"use" can't be @safe because it contains a call to "destroy".

For better understanding of the idea, I include the "use" 
template code

```d
R use(R, T)(T obj, R delegate(T) fT)
{
   scope (exit)
     destroy!false(obj);

   return fT(obj);
}
```

What's the way to ensure @safe using destroy? (if possible)
