The CPTK_IS_BASE_OF case becomes much simpler indeed, thanks. For the 
unary traits, though, I don't see an advantage in using it, because in 
some cases in check_trait_type we don't want to error out even when 
complete_type_or_else would. Unless we can check whether we are dealing 
with an array of unknown bound *before* completing the type? That is:

  if (TREE_CODE (type) == ARRAY_TYPE && !TYPE_DOMAIN (type)
&& COMPLETE_TYPE_P (TREE_TYPE (type)))

is the outcome always the same before and after trying to complete (type)?

Thanks,
Paolo.
