About 4.5 years ago, I went out on a limb and added SRFI-105 (curly infix expressions) to core Guile. Even now, I'm of the opinion that judicious use of curly infix could be beneficial for readability, but as far as I can tell, there's been essentially no uptake. If I'm wrong about that, please let me know. Although (a subset of) SRFI-105 seems like a clear win to me, I cannot say the same of either Wisp or SRFI-110 (Sweet expressions). Of those latter two efforts, I prefer Wisp, and I can understand the motivation for wanting to eliminate the parens, but to these eyes the cure seems worse than the disease. I tend to agree with Sylvain Benner, who you quote on your site as saying "I find it less readable and actually it adds complexity to the syntax because you have to deal with 3 components to understand the structure [...] So in fact you add 2 more constructs for readability which IMHO has not the expected effect on most people." Anyway, regardless of my personal opinion, I think we need to be careful not to add things to Guile that will go unused and merely contribute to its increasing bloat. I think the relevant question is: are a non-trivial number of people likely to use this? For starters, do you know anyone writing non-trivial amounts of Wisp code other than yourself? You might expect that to change if we added it to core Guile, but that didn't seem to happen with SRFI-105. So, unless Wisp is being used by more people than I suspect, my personal take on this is that we should not incorporate Wisp into Guile at this time. On the other hand, if there are sane changes that we can make to Guile that would facilitate adding support for languages like Wisp and SRFI-110 to Guile via external libraries, I would absolutely be in favor of working toward that goal. For example, I've pondered the idea of making the "reader directive" mechanism (e.g. things like #!curly-infix) easily extensible. For example, we could perhaps arrange for 'read', when encountering "#!FOO" in the input stream, to look for a module named something like (system reader-directives FOO) which would extend the reader as needed. What do you think? Regards, Mark PS: While visiting the web page <http://draketo.de/english/wisp> to refresh my memory about Wisp details, my browser tried to access port 8888 on my local machine. Looking at your site code, I see that there's an iframe element with src="http://127.0.0.1:8888/Sone/viewSone.html?sone=[...]", and also an input element with value="http://127.0.0.1:8888". You might want to fix those.
