Regarding number two, after I started using syntax coloring editors for my Common Lisp I noticed that the blue stuff (the language keywords) was surprisingly scant. ie, Most of the text consisted of my own variables and operator names. This (I guess) is especially true of functional languages and maybe also because I never miss achance to hide boilerplate with macros. So in conclusion my fellow Archers, I think real world code you write will be as long as you want it to be. No one forces you to pick short names or use the chaining:thing.
