I've never found that sticking strictly to the Law of Demeter makes your life that much easier for the reasons under "Disadvantages" in the article.

I prefer a more relaxed form of the law: you can do something like a.b().c(), where b is a method that returns an interface. I think of it as a "composite interface". You can repeat the nesting as much as you like, however it gets a little hard to read after a while.
