--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> 2010-12-17 17:40:46 UTC --- Jason, sorry for bothering: I would be interested in knowing in particular your opinion about t4, where is_constructible_mini "returns" true, that is, isn't just that errors are not suppressed (ie, more than just tsubst_flags_t arguments not propagated)
