[pro] Are you an Imager or a Filer?

Hi,

I'm continually learning Common-lisp and trying to find the best style that suites me better. I've tried 'an imager' style (cooking a an image with all required libraries loaded when required), and 'a filer' style (loading files or systems each time I fire-up a CL implementation). I'm interested to hear what others use CL. How do they manage day to day work? how do their preferred style mesh into their production pipeline (coding, debugging, deployment and maintenance)? and what makes them prefer one way over another or the mix if applicable?

Regards,

Ala'a Mohammad.
