Please clarify - can we trust this code in yajl-ruby gem yajl.rb file?

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:

• Status changed from Open to Third Party's Issue

This code doesn't come from Ruby, it comes from ruby-yajl (an external project): https://github.com/brianmario/yajl-ruby . You should ask the ruby-yajl developers about this, since it is their code.

In the future, before you file additional bugs on Redmine, please check they are bugs in Ruby itself, and not in external gems. Now that most of the standard library has been gemified, even in the standard library, you should try to find the appropriate upstream repository and file the bug there.

Additionally, only file bugs for Ruby versions that are currently supported. The example you provided shows you are using Ruby 2.0, which went out of support almost 6 years ago.
