This is probably personal preference, but I usually use an explaining
variable of defaults and have
defaults = {:width => 800, :align => :left_justify}
options = defaults.merge(options)
This doesn't mutate the existing options object but creates a new object.
I'm not sure if this is a bug or feature.
I use double quotes rather than single, but that's because I use plain
command line ruby rather than rails.
