How about this? Instead of adding further examples, I made the existing 
ones just a bit more complex (I added another 'setq' after defining the 
function 'getx' to both examples). Then I explained specifically that in 
the lexical binding example, "... 'getx' sees the current global value 
of 'x'."

Hopefully this strikes the right balance between being explicit and 
detailed about what's happening without adding too many twists and turns 
to the section. I wanted to stick with just two blocks of code in this 
section so that a reader who was skimming (or just reading quickly) 
could easily pick them out to compare and contrast with each other. 
Additional code blocks made this harder to do when I tried it.
