# Create a bunch of stuff:
ahash = {:a => 1, 'BB' => 2, 7 => 'seven', 'd' => 10}
astring = RUBY_VERSION + ' ' + RELEASE_DATE
afloat = Math::PI
anarray = ['c', 111, Exception.new('Oops')]

# Bunch it more:
anarray.push(ahash).push(astring).push(afloat)

p anarray  #  for comparison
puts '.'*107, ''

# See what yaml's y shows
require 'yaml'  #  <-------------------------#
y anarray
