  I know you *can* but it's very bad practice, and when you're a warning
freak like I am, I won't mark a variable "const" if the function will
eventually change it. Anyways, that does not changes my request, that is
to mark the fact that the data must be pre-initialized before use to
make -Wuninitialized even more useful :)
