sage: from sage.libs.ecl import *
sage: ecl_eval("(defun fibo (n) (cond ((= n 0) 0) ((= n 1) 1) (t (+ (fibo (- n 1)) (fibo (- n 2))))))")
<ECL: FIBO>
sage: ecl_eval("(mapcar 'fibo '(1 2 3 4 5 6 7))")
<ECL: (1 1 2 3 5 8 13)>
sage: list(_)
[<ECL: 1>, <ECL: 1>, <ECL: 2>, <ECL: 3>, <ECL: 5>, <ECL: 8>, <ECL: 13>]
