http://eel.is/c++draft/dcl.array#8.sentence-1 says:

Except where it has been declared for a class ([over.sub]), the subscript operator [] is interpreted in such a way that E1[E2] is identical to *((E1)+(E2)) ([expr.sub]).

Well, currently E1[E2] is not always identical to *((E1)+(E2)) valuecategorywise.

Also, can we call subscripting commutative (eel.is/c++draft/dcl.array#8.sentence-3), if in E1[E2], The expression E1 is sequenced before the expression E2.?
