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

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:

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)
