Re: [racket-users] Strange behaviour of the eq? operator in racket repl
Yes, Scheme (and therefore Racket) has eq?, eqv?, and equal?. I understand the desire for eq? and equal?, but I’ve always been skeptical of the necessity of eqv?. Either way, Scheme left this behavior unspecified, but I believe Racket specifies it (though I could be wrong). Racket has two kinds of symbols, interned and uninterned. Symbols produced by the reader, whether via read or read-syntax, are interned. Additionally, string-symbol produces interned symbols. Certain functions such as gensym and string-uninterned-symbol produce uninterned symbols, but these are not commonly encountered, anyway. Interned symbols, I believe, are guaranteed to be eq? since they’re, well, interned. There is a pool of interned symbols such that all symbols made up of the same string are all the same object, so they’re all eq?. I can’t reproduce the behavior in the original message, and I don’t think it should be possible.

Eq? may be used like eqv? in applications using procedures to implement objects with state since it obeys the same constraints as eqv?. You should use = with numbers as far as I remember.

[racket-users] racket testing on openwrt
Can someone recommend an easy way to test Racket 9.2 pre-release on OpenWrt (embedded GNU/Linux, running on a normal home WiFi router)? For example, is there a big tree of files that I could just copy onto a USB flash drive, and run with one command, and it would dump its log to a file or stdio? (I see http://drdr.racket-lang.org/help;, but I don't know whether that's what I should be using, nor what an easy way to use it would be. I'd prefer to run the tests disconnected from the Internet, if that matters.) Neil V. -- You received this message because you are subscribed to the Google Groups Racket Users group.

[racket-users] Strange behaviour of the eq? operator in racket repl
Hello everyone, So i am trying to learn scheme in my free time (unfortunately my university doesn't use scheme in their undergraduate courses) and i was comparing the equality operators in gambit and racket and encountered a strange behaviour with the eq? operator in racket. To my surprise comparing the same symbol with eq? returns sometimes a different value in the repl. I expected the return value #t. This is the behaviour: --- $ racket Welcome to Racket v6.1.1. (eq? 'l 'l) #f (eq? 'l 'l) #t $ racket --no-jit Welcome to Racket v6.1.1. (eq? 'l 'l) #f (eq? 'l 'l) #t (eq? 'l 'l) #f (eq? 'l 'l) #t (eq? 'l 'l) #t (eq? 'l 'l) #t (eq? 'l 'l) #f (eq? 'l 'l) #f --- How to reproduce this behaviour? Just start racket from the command line and type '(eq? 'l 'l), this should return #f (or sometimes #t). The next time the same expression returns #t. Whats also interesting is that with the command line option --no-jit the return value seems to randomly change between #t and #f. This seems to happen only when you type the expression into the repl. Can someone explain why the eq? operator behaves like this in the racket repl? The eq? operator shows the expected behavior in gambit but not in racket. Do i miss something? Btw a big thank you to the racket team for developing, maintaining and improving racket.
