I'd like to get back into functional programming. I learned scheme and then Lisp in school, but have had no opportunity to use them, though I have been gradually hearing great things about what using them can do for me, like Paul Graham's story about Lisp and ViaWeb.
I never once got to do anything with scheme or Lisp that interacted with the environment. How do you make a system call? How would I do output? How would I write a CGI program in Lisp? Is there a mod_scheme for Apache?
Googling for string combinations like "Lisp CGI" brings me to junk sites, so far. Any pointers? I'd like to emphasize scheme, but I can go into Lisp if necessary.
