A question about lexical binding
|
| |
For a couple of years (well, since I started learning Lisp and Scheme in my spare time) already I am trying to fathom what the real meaning of lexical scope is. I know how to use them, I program Perl at day, and I know the extent of lexical variables, and I can use them to build closures. However, I am currently going over SICP, and I am building an... more »

static, dynamic and implicitely typed languages
|
| |
I think that Lisp compiler get their power because in Lisp you usually declare implicitely the type of the argument: (person-name "John") (char "sure I'm a string" 1) (car '(sure this is a list)) (= A B) ;; sure A is a number.... That is instead of declaring the type of the argument, Lisp language... more »

(defvar *fun-table* '(("+" . #'+) ("-" . #'-) ("*" . #'*) ("/" . #'/))) (defun operate (op n1 n2) (funcall (cdr (assoc op *fun-table* :test #'string=)) n1 n2)) When I try to call the function operate in the format as follows: (operate "+" 1 2) It failed. The error message is: *** - FUNCALL: (#'+) is not a... more »
