Thus, if you want to return a pointer to a list of pointers-to-const, what you must have is a list of pointers-to-const. But you don't have such list. You have a list of pointers-to-nonconst and those list types are not interconvertible. Of course, you could transform ...
It does require you have some way to construct the object prior to calling the function, which doesn't always make sense for all objects. If you want to use dynamic allocation, the least that can be done is put it in a smart pointer. (This should be done all the time anyway) Then ...
