    On mobile: multiple top and bottom tool/nav bars that automatically show/hide themselves when you scroll. They’re invariably more irritating than if they were just pinned at the top of the page (or perhaps viewport, but ideally page - I can scroll to the top of I want it back)

    On desktop: animations tied to scrolling.

    Anywhere: any kind of popup, modal, etc that I didn’t click on something to get. Please fuck alllllllll the way off.

    The browser implements the text selection behaviour, but how infuriating it is depends on how convoluted your page construction is.

    On a simple page with no floats, overlaid elements, negative margins, absolute positioning, hidden stuff, and other css layout tomfoolery, it’s perfectly predictable. It’s only when designers do designer things does it start to break down.














  • The way it works is that there’s a symbol table entry for “foo” which has a slot for a hash, scalar, array, glob, etc.

    That leads to some super weird behaviour like, for example, if I declare a scalar, hash and array as “x”:

    $x = "sy";
    %x = (foo => "mb");
    @x = ("ol", "s!");
    

    You can access them all independently as you’re aware:

    say "x: ", $x, $x{foo}, @x; # Outputs:  x: symbols!
    

    But what’s really going to bake your noodle is I can assign the “x” symbol to something else like this:

    *z = *x;
    

    …and then the same thing works with z:

    say "z: ", $z, $z{foo}, @z; # Outputs:  z: symbols!
    

    Oneliner if you want to try it:

    perl -E '$x = "sy"; %x = (foo => "mb"); @x = ("ol", "s!"); say "x: ", $x, $x{foo}, @x; *z = *x; say "z: ", $z, $z{foo}, @z;'
    

    Congratulations! You now know more about one of Perl’s really weird internals than I’d wager most Perl programmers (I have literally never used any of the above for anything actually productive!)

    You mean the fact that you can have a hash called %foo, an array called @foo and a scalar called $foo all at the same time? I agree that’s a weird choice and there’s potential for insanity there, but it’s pretty easy to just not do that…

    20+ years of Perl experience and while Perl has a load of idiosyncrasies that make it harder to work with than other languages, I don’t think that particular one has ever caused a significant problem.
