Title: Reverse %w and %i guidelines to maintain consistency for arrays.

It seems odd to me to have different syntax for defining arrays depending on the contents.

STATES = %w(California Nevada Arizona)
vs.
YEARS = [1850, 1864, 1912]
or even
STATES = ['California', 'Nevada', 'Arizona', 'New Mexico']
