Thanks David, and thanks for AUCTeX! 

I look at the code in mic-paren.el and it starts with

(eval-when-compile (require 'cl))

This seems to comply with the official policy advised at 
<http://www.gnu.org/software/emacs/manual/html_mono/cl.html#Overview>

in case avoiding the use of mapcar* proves troublesome, couldn't auctex require 
cl in the same manner mic-paren does? 

(and I have now learned what "cl" means...)
