Hey,

I'm going through the book and I wanted to share errata/typos I've found through the book:

Chapter 3, just after the explanation of fold you can read: "Summing is done using a pure, higher order function, +, so there is no chance of a side effect in the summing function causing unforeseen problems."

But "+" is not a high order function, the high order function here is fold. "+" is pure but not a high order function.

In the same chapter, this sentence has a huge typo:

"Thanks to a recently signed contract with technology consultants Vulture Corp., you know have access to some sensor data about the movement of land-bound animals (Figure 3.3)."
