    What that garble of symbols does, is that it defines and calls a function named :, which calls itself twice.

    The syntax for defining a function is different in Fish, so no, this particular garble will not work:

    But it is, of course, possible to write a (much more readable) version that will work in Fish.

      you can write a more readable version in any shell, it’s intentionally unreadable

        Yeah, I meant, as an attacker, you couldn’t come up with a similarly unreadable version.

        At least, as far as I can tell, defining a function requires spelling out function and seems to require being defined on multiple lines, too.

        It hails back to the early days of the ampersand, from when it was basically still just Latin “et”: https://commons.wikimedia.org/wiki/File:Trebuchet_MS_ampersand.svg

        Personally, I do like this font (Fira Mono+Sans), because it still looks professional, without being so boring that I get depression from looking at it.
        But yeah, that ampersand is pushing it a bit, as I’m not sure everyone else knows that’s an ampersand…
