Lambda expression appearing in a function call

Ok, I got this to work : a lambda expression appearing in a function call :

CL-USER 2 : 1 > ((lambda (x) (* x 2)) 3)
6

I know its not as big a deal as creating the theory of relativity, but I got something to work in Lisp

Congratulations.


That said, while you're being pampered by Lispworks, write down on your
to do list to learn some about unix. You can hardly call yourself a
programmer (even amateur), if you don't know how to deal with a CLI and
do some basic system administration tasks.
