Ruby implicit block capture

def new(url = nil, options = nil)
  block = block_given? ? Proc.new : nil
  options = options ? default_connection_options.merge(options) : default_connection_options
  Faraday::Connection.new(url, options, &block)
end

# And it should be used like this:

conn = Faraday.new(:url => 'https://www.smartly.io/developer') do |faraday|
  faraday.request  :url_encoded             # form-encode POST params
  faraday.response :logger                  # log requests to STDOUT
  faraday.adapter  Faraday.default_adapter  # make requests with Net::HTTP
