Scoped Class Instance

[Nicolas Silva]

You can use structs for this kind of problems, somethin like

struct Scoped(T)
{
    ~this()
    {
        //handle deallocation here
    }
    T inst;
}

if you create a Scoped!MyClass in a scope, the struct's destructor
will be invoked whenever the program leaves the scope, even if it is
because of an exception.
