True, 'new LocalDate[10]' will continue to allocate an array of nulls. The default instance is only relevant when someone does 'new LocalDate.val[10]'.

Regardless of the syntax, if there exists an inline type for instances of an inline class ('LocalDate.val' above), there will also be a semantic question of how we initialize fields/arrays of that inline type.
