For the value, they also missed the opportunity to do something sensible when moving to C++ attributes, what a pitty. For a concrete guideline in that jungle, when (= which version) do you expect this patch to hit distribution? Will it be in clang-18 once that is released? Can we expect a similar feature, let's Call it clang::deallocator_function in a future version? Thanks Jens -- Jens Gustedt - INRIA & ICube, Strasbourg, France

It does appear that this is on track for clang 18, but it hasn't finished review yet, so I cannot promise that of course.  At the moment, nothing like a `clang::deallocator_function` is proposed, so unless someone does the work to implement and propose it, we don't have a plan to do so.
