Awesome article.  I especially liked the gory detail on how expression
trees are evaluated. I've been writing nix expressions for a few months and
already knew most of the material you covered, but that section really made
it clear how and why lazy evaluation works the way it does.

The only thing I didn't enjoy was the "I lied" motif. Especially after the
lazy-lists thing, it made me wonder if I could believe what I was a
reading. The general technique of over-simplifying and then introducing
layers of nuance is good, but I think you over-did it.

I'm really looking forward to the next article!
