       A asynchronous code often have deep nested callbacks, therefore it is
       tangled and hard to change. This module help to converta a code like
       following to some more readable form. Also, with "chain" you can easily
       skip some unneeded steps in this thread. For example jump to log step
       after the first failed query in the chain.

       without chain:

           sub f {
               ...
               some_anync_call @args, cb => sub {

            ...
            log(...);
        };
