I'm an architect and LISP programmer, and started with Perl as second language to deal with my lisp build system, documentation and localization issues. perl4 then. I dropped C and switched to Perl for low-level stuff, and kept LISP for the hard problems.
Now that I do not do tricky and hard problems anymore and I used C, VB, PHP, Python and assembler extensively and commercially, I switched to Perl as my first language, and I also maintain parrot a bit and some hundreds of cygwin packages.
I'm maintaining the perl compiler and optimizer modules, created p2, and do not do any GUI or hard problems anymore, only the clisp-gdi module.
