The thing to keep in mind is that Slang is simply C written in  
Smalltalkish syntax. This is rather confusing at first, so take a good  
look at the generated C code and try to make sense of it. You do have  
to ensure all your type declarations make sense to the C compiler,  
etc. There is no magic about this, it's straight-forward C.
