First of all, we have to decide if make-alien makes an alien of the
specified type and returns a pointer to it, or makes an alien of
whatever type the alien (pointer) type points to.  I kinda like the
first option better.  Then the optional argument would just mean make
n aliens of this type and return a pointer to the first.

So (make-alien int 10) is valid and meaningful.
