           Summary: static destructors should be allowed in function
                    bodies
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd

Here is why : as we can hide static variables in function bodies there should
be a way to cleanup them.

A way to do that would be to allow local static destructors, for example

```d
struct S { }

S getS()
{
    static S result;

    static ~this() // run when the program finishes
    {
        destroy(result);
    }

    return result ? result : (result = new S);
} 
```
