Outdated chapters

[masterdezign]

Function double introduced in Chapter 2.11 does not work anymore in PSCi.

$ pulp psci
PSCi, version 0.11.6
Type :? for help

import Prelude
> let double x = x * 2
(line 1, column 20):
unexpected end of input
expecting ., {, ::, infix expression, "where", indentation at column 5 or "in"
Declarations in PSCi no longer require "let", as of version 0.11.0

Chapter 3 is also outdated. Trying to reproduce steps from page 16:

$ cd chapter3
$ bower update
$ pulp build
