Try what you learn from the specs right away on the REPL! 10:53:52 R5 is lovely 10:53:56 But sicp doesn't teach scheme, it teaches programming. 10:54:05 pjb: precisely :) 10:54:13 As compared e.g. the C99 spec, R5 is really quite small, and very simple to read. 10:54:55 How long is R6RS? 10:55:32 skip it, read r7rs :-) 10:56:07 ok, i'm not a schemer, what's so bad about r7rs? 10:56:22 in the past few days I've been reading the racket guide and it sounds great 10:56:29 and that's r6 right? 10:56:45 r7rs is good. 10:57:06 pjb: yeah but why is r6 bad? a lot of people seem to hate it 10:57:49 Read what they have to say about it. I haven't read r6rs. 10:58:31 you still suggest to skip it 10:59:10 r7rs is newer than r6, (duh!), so one could argue there's no point dealing with an older spec, you might as well go for the latest. 10:59:35 well but you still suggest to read r5, which is arguably outdated 10:59:39 On the other hand, both r6 and r7 are much bigger than r5, and add lots of new things, without really removing or changing much of what's already there. 10:59:51 So for something small to start with, r5 is a good starting point. 11:00:26 Lajjla [~Lajla@2001:0:5ef5:73b8:1405:221a:ae33:eb94] has joined #scheme 11:00:28 I mean while I understand the argument for minimalism 11:00:44 I find myself having much more fun with somethin like racket than just a bare r5rs scheme 11:00:52 Ah, well do that then :) 11:00:55 ijp [~user@host31-53-168-239.range31-53.btcentralplus.com] has joined #scheme 11:01:00 r7rs is good because it has a small part and a big part. 11:01:16 I find I prefer starting at r5, because it's quite small and I get a good hang of the general ideas, then I can move on to r7 building on top of that 11:01:40 yeah but I'd still like to know why you are all ignoring r6! eheh 11:01:55 And it seems a common thing.

Notably in writing macros. 12:30:55 defvar and defparameter define always global variables. 12:31:25 In CL, there's no confusion between global operators and local operator. For local scope you use LET LET* LABELS and FLET. 12:31:33 for global DEFsomething. 12:32:32 what confusion? 12:32:50 In scheme define is sometimes global, sometimes local. 12:33:11 This is misleading. 12:33:19 I disagree 12:33:25 scope is clearly delimited in scheme 12:33:43 rather than allowing arbitrary jumping to a higher level 12:34:06 *ijp* stops before this gets out of hand 12:36:53 ijp: oh...... 12:37:09 ijp: We also plan to finish support for R5RS, but we will not be providing support for R6RS. 12:37:12 ijp: mit-scheme 12:37:28 Is define-syntax the same as defmacro? 12:37:32 will they ever finish? 12:37:46 Asphodelia: yes, and no 12:37:57 it does define a macro, but scheme macros are not CL macros 12:38:02 ah. 12:39:00 ijp: so? 12:39:10 ? 12:39:36 masm [~masm@bl17-207-242.dsl.telepac.pt] has joined #scheme 12:40:12 Asphodelia: syntax-rules is the least-common denominator, since it's in the R5RS.
