operator [ int, int ]

Which language are you talking about?

Original post by thedustbustr Is it possible to overload the subscript operator[] and the comma operator, such that you could call myObject[2,5] (similar to python string splicing, mystr[2:5])?

Assuming you mean C++, you can't overload operator[] to take 2 parameters, and you can't overload the comma operator for built-in types, however, you can if one of the operands of the comma operator is a type you define. In that case, you can use expression templates instantiated with each comma operation. Alternatively, if you aren't used to expression templates and you only ever want 2 operands (never 3, etc), you can just make your type have a constructor taking 2 operands.

In other words:

// Prefered solutionmyObject[ your_type(2), 5 ];myOtherObject[ your_type(2), 5, 6 ];// Or, the alternative solutionmyObject[ your_type(2, 5) ];myOtherObject[ your_other_type(2, 5, 6) ];

Note that the first solution allows you to easily work with the same "your_type" to start the expression, whereas the alternative solution requires a different type depending on the number of operands and is not easily expandable for more parameters without having to resort to preprocessor metaprogramming, though if you only want it for 2 or 3 parameters, it will be easier to implement.

A better approach might be to overload operator() instead.
