Overload of operator[]

I was trying to create a "readonly" operator[] in public scope and a
"write" operator[] in private scope of the class. But the compiler
seem intent on trying to use the private version.

Am I expecting to much from the compiler or is it not possible for it
to resolve the correct version of the function.

TIA
