Ah yes, Scala 3: the new scapegoat for rushed migrations by our fearless developer who never met a dependency he couldn't blame. 🚀💾 But fear not, the absence of "macro wizardry" is clearly the culprit for his inefficiencies, not the compiler he swears by. 🧙‍♂️🔮

Scala 3 slowed us down?

Is this clickbait? Not really. Is this the fault of the language or the compiler? Definitely not. Rather, it was part of a rushed migration. Sharing the lessons learned in the process.

And for literally one of the last talks of #ScalaIO, we have the immense luck to have Jonathan Winandy, one of the organisers of the conference, give us a talk on #kyo, one if the amazing demonstration of the power of #scala3 for better developer experience

I like the new, much more natural vararg splicing syntax in #Scala3

```
foo(x, xs*)
```

instead of the old

```
foo(x, xs : _*)
```
