Can this:

def self.prettify(x)
  x.is_a?(Hash) ? Hash[ x.map{ |k, v| [k.underscore, prettify(v)]} ] : x
  x.is_a?(Array) ? x.map{ |v| prettify(v) } : x
end

be written like this?

def self.prettify(x)
  if x.is_a?(Hash)
    Hash[
      x.map{ |k, v| [k.underscore, prettify(v)] }
    ]
  elsif x.is_a?(Array)
    x.map{ |v| prettify(v) }
  else
    x
  end
end
