Today, instead of announcing a new feature, we would like to ask you about a possible new one. 🔎
In some other languages, it's possible to evaluate inline with the `>>>` symbol in a comment. This gives you a quick ability to evaluate some code. Should we add it to Metals?

Hey, #ScalaCLI v1.10.0 is out! 🚀
The changes include:
Scala defaults changed to 3.7.4 and 2.13.17, support for the new Scala 3.8 REPL artifacts (to try with 3.8.nightly versions), support for adding extra directories to a docker image, a number of fixes, internal changes and dependency bumps. (1/2)

And another code action will allow you to quickly switch any map/filter chains into a collect method invocation.

We also have two new code actions. First one will allow you to convert any infix notation to a standard one. This is not enabled for symbolic operators.

There is more! If you are a fun of quickly checking currently worked on test case, it's now possible to run the closes test case or method to the current cursor position!

Did you ever get annoyed that you need to reimport everything when copying between different files? Worry no more! Metals will now try it's best to take care of that for you.

Enabling the new closing labels inlay hints will allow you to easily track where each method or class body ends.

New 'copy FQN' command will allow you to get the fully qualified name for any class, method, object or value. This can later be used in places like scaladocs. For example when invoked on the "main" method, you will get a result in for of "com.example.Main#main"

Ox feature tour, day 19: because it's direct style, integration with OpenTelemetry (metrics+logging+tracing) "just works"! To propagate tracing context inside concurrency scopes, you only need a single switch at your top-level `OxApp`!

Ox feature tour, day 18: `.pipe` and `.tap`, even extremely simple, are suprisingly useful! And there's no overhead: these are inline methods, hence a "zero-cost abstraction". Bonus: discover the `debug`, `.discar` and `.tapException` methods!

Ox feature tour, day 17: converting exceptions to `Either`s, and vice versa is trivial thanks to the inline `.catching[]` and `.orThrow` methods. A panic at one level, might become an expected error at another!

Ox feature tour, day 16: we propose error handling based on "panics" (exceptions) and "expected" errors, represented as Eithers. Working with the lattter is ergonomic thanks to Scala's boundary/break, and its Ox-provided specialization to Eithers using `either: and `.ok()`

Ox feature tour, day 14: declarative concurrency in flows - virtual threads are started (and terminated on error) safely, without ever needing to touch concurrency scopes! Signalling an error is as easy as throwing an exception.

This is the select you might know from Go: complementing the goroutine equivalent - forks (virtual threads) within a concurrency scope
