Randomize array element order in-place.
Using Fisher-Yates shuffle algorithm.

Array.prototype.shuffle = ->

Instructions: 

In sublime, in the menu find Preferences => Settings - User. 
This will open a file, and while this is not the file we want, it is in the correct directory.
NOTE: Please be careful to follow these in the correct order, rather than risk overwriting your user settings!

Do File -> Save As, and resave the file as Pry.sublime-snippet
Delete the content and paste the first file below in that file, and save.

# My answer at the time was to do something like this
[[nil]*3]*4
#=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]

# The next question was whether I knew some initializer to do that for us.
# Apparently, there is:
Array.new(4) { Array.new(3) }
#=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]

# But that wasn't the brainwave my brain came up with just now.
