An amusing issue I came across with #emacs define-word package: askingfor the definition of the word "backslash" triggers an error, becausethe definition contains a literal backslash character that's notescaped properlyhttps://github.com/abo-abo/define-word/issues/32

Ever heard of executable-make-buffer-file-executable-if-script-p?I wrote a short post about the history of this #Emacs function and my(perhaps novel) way of utilizing it to avoid typing "chmod":https://eshelyaron.com/posts/2023-04-08-making-shell-scripts-executable-just-in-time.html

Here's a fun little experiment I'm currently trying with #Emacs,applying different background colors to buffers with certain majormodes, like the *Help* buffer or `shell-mode` buffers and friends

I thought I'd try out #adventofcode this year for the first time.Day one was kinda fun, I solved the first part with only an #Emacskeyboard macro and one line of #Lisp. The second part was already alot trickier, but nothing that a quick #Prolog DCG can't solve :)

@galdor Sure, it's not the prettiest, but you can find it here:https://git.sr.ht/~eshel/aoc2023/tree/master/item/prolog/challenge2.pl

@galdor I kinda agree, but note that the ability to fullyconceal some definitions opens the door for optimizations that youwouldn't get otherwise, and there's power in that.So should a language stop you from concealing stuff when you really want to?

@galdor Inlining of the concealed definitions, and subsequentspecializations. Of course you can do that and keep the non-inlineddefinition around, and expose that, but then you're left with a(often) redundantly increased memory footprint.

@galdor"yes, it uses memory, but nothing compared to the extra memoryconsumed to copy this function code at each inline called."Well, not necessarily, sometimes you have only a few relevant callsites, and you can specialize each of them so the memory footprint isactually reduced. But I agree with you that..."It is as always about control, with developer feeling that they haveto stop others to use specific constructs."So it's really a social problem, more than a technical one. My pointis basically that there's nothing wrong with a language allowing youto conceal stuff, since in some (admittedly niche) cases that's a goodthing to do. The problem is with people leveraging this mechanism ininappropriate circumstances.
