The problem with this is that you have to learn a new "Lisp replacement" every 5 years.
I prefer to write boring code in something like the intersection of CL, ISLisp & ELisp (in lexical scope mode). Rarely even use macros, although on the other hand I have experimented with design-by-contract. If you need libraries, the starred "community pseudo-standards" from the awesome-cl list have always done the job for me. Then you have to use CL (realistically, sbcl nowadays), but that's fine too.
