[CHAPTER 1] Array.index does not appear to exist?

[cowboyd]

Trying to follow along with the examples, I cut and paste the imports into the repl from Product.purs

And then tried to insert the first examples into the repl. The first few worked, but it looks like Array and Map aren't in scope. I must have missed some critical piece of setup.

I was able to get it working by adding the following to my real snippet.... should this be included in the recommended snippet for the book?

import Data.Array as Array
import Data.Map as Map

Yes, I messed up by not listing imports. I'll fix that chapter in the next release.
