Thanks for the pointers. I don't have too much time today to think about 
this ( public holiday and I'm going out in the sun ) but I know when
I do I'll want to know the concept here behind lists. Are they real
lists as in Ruby Array which I doubt or abstract concepts like
the Church Numerals.

I'll take a look Monday and see if I can understand more.
