Is it possible to call a constructor on data that has already been
allocated?  I have a buffer that I want to put some objects into,
but I don't know what objects and their order until runtime.  I can
think of a few ways to do this -- cast the contents of the pointer
into the type and let the casting function do the work, or create an
auto variable, then assign it to the contents of the buffer.  Is there
a better way?
