Hm, interesting. Just tried it in Rhino, it works, code of my "hidden"
functions is printend. So users can see what internal variables and all
I do use there ... Hmmm.

Would be really nice to have something to prevent this
toString()/toSource() stuff, if needed! By overloading the
toString()/toSource() or so, but how to do this for functions? Something
like the ClassShutter mechanism would be helpful ...
