Regardless, the limitations of the language and the solutions 
brought up have been discussed on the forums for years. Getting 
some kind of pathway forward is really what is needed. Breaking 
the problem that Andrei brings up into a smaller one, i.e. 
writing a @safe appendable vector that works as much like a 
built-in one, is a useful start.
