[dmitriklein]

Please clarify - can we trust this code in yajl-ruby gem yajl.rb file? (# TODO: this code smells, any ideas?)

class Encoder
def self.encode(obj, args, &block)
# TODO: this code smells, any ideas?
args.flatten!
options = {}
io = nil
args.each do |arg|
if arg.is_a?(Hash)
options = arg
elsif arg.respond_to?(:write)
io = arg
end
end if args.any?
new(options).encode(obj, io, &block)
end
end
end

========= it generates following error:
