so why not use "ordinary" views, eg. containers of pointers?
it's not difficult to lay out std::vector<Foo*> s.t. no memory allocation occurs (except once). It strongly depends on your application. E.g. inserting and removing elements in the middle of a sequence rather forbids the using of std::vector due to performance reasons. And in an answer to Frank I discussed the using of std::list together with pool allocators. I don't argue, that intrusive containers are the swiss-army knife they used to be in the C world. In fact, the application area is very limited in the C++ world, since you can choose from a wide range of approaches regarding sequences. However, IMHO intrusive containers certainly belong to that range and sometimes they even aren't replaceable without a loss of efficiency.
