I saw these procedures in the source, but haven't figured out how to use them 
yet. :-(

No real reason, at least not at this moment; I was just trying to get an idea of 
how "introspective" Chicken is.  Like, in Python you can get *some* information 
about a defined function (like its signature, bytecode, etc), and in languages 
like Io you can get the actual source.  I figured that it would at least be 
technically possible to get this kind of info.  I don't have a real purpose for 
it at this moment though. :-}
