Re: [racket] TLS "atom?" definition for Scheme does not work in DrRacket

Alex Yes, that is what happens. (with BSL) But if I remove the erroneous (define and...) then it again flags pair? as "function not defined". I think maybe it only prints one error msg, the last one found. Sorry for the delay. I am rebuilding the laundry room here at my sister's house during the

Re: [racket] windows-1252 charset decoding

I see that the documentation suggests that (entity-charset) is supposed to return a symbol. However, it nearly always returns a string. In particular, it appears to me that it returns a symbol only when it returns its default, 'us-ascii. I feel compelled to repair this, but there are two ways to f

Disclaimer: this question is both a real question and me trying to push the type system to its limits, so I’m not really expecting to get a satisfactory answer. I posted a question on Stack Overflow here , but I’m guessing that this is unfortunately
