structured-data's Issues

Authors gets defined twice

ex. 24 asks to "Write the function (authors books) that returns the authors of every book in books as a set." but later on after ex. 30 "(def authors #{china, felleisen, octavia, friedman})" data is introduced for testing purposes which gets masked by the previous function definition.

solution on exercise 22 does not work on 1.6

The solution to exercise 22 seems to be :

(defn old-book->new-book [book](let [authors %28get book :authors%29]
%28assoc book :authors %28set authors%29%29))

but when you do this in 1.6.0 this is the output :

{:title "Wild Seed", :authors #{{:death-year 2006, :name "Octavia E. Butler", :birth-year 1947}}}

Is it a idea to update this course to the newer version.

Problem with the Exercise 29

Hi there!
I'm having a issue with the test for the Exercise 29. Look at the result of the test (lein midje):

FAIL "books->string" at (structured_data.clj:317)
Expected: #"3 books. The Little Schemer, written by (Daniel Friedman (1944 - ), Matthias Felleisen|Matthias Felleisen, Daniel Friedman (1944 - )). The City and the City, written by China Miéville (1972 - ). Wild Seed, written by Octavia E. Butler (1947 - 2006)."

Comparing with the result in the article:

(books->string [little-schemer, cities, wild-seed])
;=> "3 books. The Little Schemer, written by Daniel Friedman (1944 - ), Matthias Felleisen. The City and the City, written by China Miéville (1972 - ). Wild Seed, written by Octavia E. Butler (1947 - 2006)."
