@rob_mcrobberson We could have had both before everybody decided that equalization is a myth. 🔻

@ChiefScientist The type checker caught so many bugs that I became one.

[Sarah Gerweck @SGerweck]

@rob_mcrobberson +1. You can grind for a while, and sometimes it’s a good idea. In my experience, doing it for extended periods of time is a Faustian bargain that will sabotage you more than you expect, including in the project you’re grinding out.

@yolwoocle_ Split Fiction has a two-player segment that feels a bit like this. It’s pretty cool but a little disorienting.

@julianhyde Do you need a flatMap variant as well?Some(None) complicates this goal a bit.

@stanfordNYC “What you recall learning” changes this question in a profound way.

[Sarah Gerweck @SGerweck]

@QuinnyPig Oh you’ve stayed with us before? Great, let me make sure to direct you to the pool for your one-night stay on business.

@classfrenemy I really like drizzling and tossing popcorn with a mixture of butter and Tabasco. It’s not for everybody and it can get a little gooey but the flavor is fantastic.

@julianhyde @morel_lang I wish it were spontaneous inspiration, but I find the art of engineering in 2026 is often about being good at collaborating with AI. 🙃

[Sarah Gerweck @SGerweck]

@julianhyde @morel_lang Carats also work equally well if you allow descending or less ordered iterations, but the comparisons feel weird in those cases.

[Sarah Gerweck @SGerweck]

@julianhyde @morel_lang I kinda like this. Gemini also suggested carats or tildes as an exclusion operator `3 ..^ 7`. More arcane but maybe cleaner 🤷🏻‍♀️
(I don’t like tildes for this because it feels fuzzy and I think this is a discrete process)

[Rudransh @rudranshstwt]

It's simple

@julianhyde I don’t know that I’d call bash a CLI. That’s a little meta to me: I mostly use a shell as an enabler. I *would* call git’s command line a CLI because it’s the command line way to interface with all my hashes & labels.
🤷🏻‍♀️ not sure this is well principled

@Maelophilia Turns out the racer was named “rosebud.”

[Sarah Gerweck @SGerweck]

@SeanTrende Cars now last about twice as long as they did then, which makes resale value more relevant. In part, people buy all the same colors because they’re easier to sell.

@ApriiSR It’s all fun and games until they start eating pizza and getting in street fights.

I’m sorry you had this one coming.
(You’re obviously right about countability if we assume language has a fixed set glyphs.)
