That ought to be: "you have got the wrong language".
Worshippers of CL (COBOL-Like) and LOOP have very poor
language skills.

you should learn loop

Worshippers of CL (COBOL-Like) have no affinity for Lispy
programming, so they are irresistibly drawn to the feculence
of LOOP as a fly is drawn to a turd.


Here's an example:

btw, I believe the thing that got me to look at loop was that it
provides efficiency for free, which is rare in cheats:
 
    (loop for x in them
          when (yada x)
          collect x)
 
vs:
 
    (let (out)
       (dolist (x them (nreverse out))
          (when (yada x) (push x out)
 
If I had learned Lisp from PCL I would have grown up with loop as a
native sub-language and not gone seven years without it.

newLISP:

(filter yada them)

Example:

(filter odd? (sequence 0 22))
 
(1 3 5 7 9 11 13 15 17 19 21)

(clean odd? (sequence 0 22))

(0 2 4 6 8 10 12 14 16 18 20 22)
