In C#, an array marked 'readonly', as in:

public readonly bool[] array = new bool[8];

would allow individual members of the array to be modified while
protecting the array reference itself from being changed.  That is, I
could do this:

array[0] = false;

but not this:

array = null;

However, it doesn't seem like the 'initonly' keyword in C++/CLI does
exactly the same thing.  If I do something like this:

public ref class Thing
{
public:
   Thing();
   void SetBool();
protected:
   initonly array<bool>^ bArr;
};

Thing::Thing()
{
   bArr = gcnew array<bool>(8);
}

void Thing::SetBool()
{
   bArr[0] = false;
}

I get a compilation error about using an 'initonly' field as an l-
value.  What's the right way to go about this?
