Well, that's not exactly the plan.

The problem we have is that we need all of the builtin libraries (those 
coded in C - classes like Array, Hash, String, ...) to work with 
Ruby/Parrot.  So instead of hand-coding them all over in Parrot IMC (a 
huge effort in itself), we're thinking of somehow parsing the Ruby/C to 
translate it into IMC.  Now it'll probably turn out that it takes us as 
long as it would have to hand-translate, but it'll be a lot more interesting 
and the resulting code will probably be useful for other projects besides 
Cardinal.

A project for doing this has been started at:
http://rubyforge.org/projects/rubyclconv/

All the best stuff results from some crazy idea ;-)
