<html> <head> <style></style> </head> <body class='hmmessage'><div dir='ltr'> <br>Sorry Shriram, i didn't mean to insult you or anyone else, but my poor english prevents me to express myself clearly. Still, i will try to explain what bothers me with the way Racket prints quoted expressions and I hope that you'll understand what i want to say:<BR><br>Suppose that we enter expression (quote (1 2 3)) in REPL. Let's see what's happen next:<BR> <BR>1) Lisp reader reads what we entered and converts it to his own internal representation of list. That list it passes to evaluator.<BR> <BR>2) Evaluator analyse given list and recognize that it contains a symbol quote at its first position, which is signal to lisp that it shoud return its (only) parameter untouched. So, evaluator does just that: as result of evaluation, it returns a list (1 2 3).<BR> <BR>Hence, I think it would be reasonable that REPL print back just that, (1 2 3), as in CL or Clojure, and not '(1 2 3) as in Racket, because quote is already "consumed" in step 2) when evaluator "eats" it while processed the quote special form. For me, it's just plain wrong to print '(1 2 3) because quote is already gone.<br><BR><div>> From: sk@cs.brown.edu<br>> Date: Sun, 18 Sep 2011 12:22:27 -0400<br>> Subject: Re: [racket] Quoted expressions in #lang racket<br>> To: racketnoob@hotmail.com<br>> CC: users@racket-lang.org<br>> <br>> I used different words than Matthias because we were trying to offer<br>> somewhat different explanations of what is happening.
