Btw if this change is intended, then it looks like the changes in section 10.2 [1] must be dropped as well
The array type of a variable depends on the bracket pairs that may appear as part of the type at the beginning of a variable declaration, or as part of the declarator for the variable, or both. Specifically, in the declaration of a field, formal parameter, local variable, or record component (8.3, 8.4.1, 9.3, 9.4, 14.4.1, 14.14.2, 15.27.1, 8.10.1), the array type of the variable is denoted by <...> Now, this text is inconsistent with 8.10.1.
