Issue description:
I've filed a Clang issue that it erroneously accepts

int main()
{
    using IA = int[];

    IA{ 1, 2, 3 } + 0;
}

but was asked to promote this to a CWG issue.
Current wording doesn't allow array prvalues as the binary + operands, neither there is wording requiring the array-to-pointer/temporary materialization/whatever conversions on such an operand.

Personally, I think such meaningless code should not become well-formed, thus

Suggested resolution: NAD
