Hi,
Used CL professionally from 2008 to 2017, now working mostly with Java and a little bit of Perl (yes, Perl as in Perl).
Transitioning to Perl was hard, but after about a year I grew to have some respect for it. Moose is actually a pretty developer friendly OO framework, and it reminds me in many aspects of CLOS. Now Java... That has been a hard transition. Even with all the niceties they've been introducing since Java 8 (the Streams API for example), it's just a pain in the neck. Testing for example can be extremely painful, especially when working with legacy code with lots of anti-patterns (mocking and stubbing is a nightmare in some cases). And even with all the improvements to the language, it still encourages a great deal of verbosity.
Anyway, I still hang on to Emacs and use Emacs Lisp occasionally for throwaway scripts. I do miss CL though. I wish there were more CL jobs going around.
Cheers,
