Use cl-lib instead of cl.el

[syohex]

There are both cl-lib a function(cl-mapcan) and cl.el a function(gensym), macros(loop) in original code. And you should not use eval-when-compile because this code uses cl-lib function(gensym).

Hi syohex,

thanks for your pull request. I merged it. Can you recommend anything where I can read up about these kind of issues. E.g. what's the state of the art in Elisp development?

Thanks, Roman

And I recommend you to byte-compile your package files. To byte-compile tells you

• coding mistakes
• bad coding style

etc.
