Re:C++17 creates a practical use of the backward array index... by HelloNurse on Tuesday April 04, 2023 @04:47AM (#35436852)
In the competing array indexing syntax

  *(a+b)
there is the same evaluation order issue, and they should have the same behaviour: is a evaluated before b or the compiler is allowed to choose an order? Clearly it depends on the rules for

  a+b
which are more important than the special case of array indexing.
