So what would it be? The result ++i does not undergo intergral promotion. A
better question might be to ask about sizeof(+i), which does force integral
promotion.

This is quite subtle. Both the ++ and the + are defined in the unary-expression
syntactic unit. The only syntactic difference is that the ++ recursively takes
a unary-expression, whereas the + expects a cast-expression.
