The drawback of this approach (compared to using just the one intermediate
language, CIL) is that it is less secure, because it relies on a larger
trusted code base.  Instead of needing to trust just one interpreter,
you need to trust all the different languages interpreters.  Bugs in
the Ruby interpreter, for example, could result in security holes.
