Because it forces you to handle the empty case. With List you can Just Forget (TM) :)

To be fair, their whole fund is 100k, which is roughly 0.01% of their last year's profits.

Of course, they could have. But is 0.01% of your profits is really make-or-break situation? Their profit margin is 7.2% based off the 15.6 billion in revenue. Whilst that 0.01% could employ someone working full-time on TL stack for a year.

You could donate to a 100 projects and still only have 1% of your profits eaten up.

To bring that to a personal level, if your NET income is 3000 eur / month, that's 360 eur/year or 30eur/month (at 1%). At 0.01% it's 0.3eur/month.

For 2024, Spotify posted net income of €1.138 billion (versus a net loss of €505 million a year prior) on revenue of €15.673 billion, up 18.3%.

1.138e9 × 0.01 / 100 = 113800 eur.

Of course they could have not donated. But IMHO the model isn't sustainable. That's why I'm personally in favor in licenses that charge money from large corporations if you actually start making money with the underlying OSS software.

Imagine the world if everyone paid 0.01% of their profit to TL.

Turns out there are other languages like this too: github.com/apple/pkl/di...

No. Seems pretty recent, I searched for options in 2021-2022. Awesome find!

Although I still wish there was a schema based format. Having no docs or autocomplete in a complex multi file configuration that is built from templates is quite a suffering.

Dhall seems to fit the bill, but it does not have a scala port.

Ammonite seems like a fit, but I could not make it work 😕

Hocon is great when you have complex but human editable configurations. Like vehicle configuration in a game server, for example.

For setting a database URL I use ciris 🙂

Well, better than nothing. But it is amazing that a company worth billions of dollars can't donate more 🥹

IDK, codeium's autocomplete works pretty well for me.
