valhalla-docs VS Dagger2

What isn't clear for me from https://github.com/openjdk/valhalla-docs/blob/main/site/design-notes/state-of-valhalla/02-object-model.md is whether or not value types will indeed be headerless.

Regarding type erasure, see https://github.com/openjdk/valhalla-docs/blob/main/site/design-notes/in-defense-of-erasure.md for a justification. Note in particular that not doing erasure would have forced languages like Scala to follow Java's semantics. In cases where erasure is actually a problem, you can work around it with classes like https://fasterxml.github.io/jackson-core/javadoc/2.2.0/com/fasterxml/jackson/core/type/TypeReference.html.

Here's a (relatively recent) post on type erasure from the lead of the value types project at Oracle https://github.com/openjdk/valhalla-docs/blob/main/site/design-notes/in-defense-of-erasure.md

If you want to read something a little more formal and fleshed out, try scanning through this document, and then come back again and tell me that Brian doesn't understand your suggestion.

I haven't been following it incredibly closely, but I have checked in from time to time. It's a hard problem, but there's a lot of real progress (https://github.com/openjdk/valhalla-docs/blob/main/site/desi...).

I'd wager that it will ship by the next LTS, in 2024.

Quotes from here

There used to be a thing called "releasable references" which was that. It was removed, though: https://github.com/google/dagger/issues/1117

As said in the title, we will focus on the dependency inversion principle and one of its application : dependency injection. For production-ready applications, it would be better to rely on a framework and not implement its own container. For it, the java ecosystem have 3 frameworks available : Spring, Guice and Dagger.

At Reddit, we use Dagger 2 for handling dependency injection (DI) in our Android application. As we’ve scaled the application over the years, we’ve accrued a bit of technical debt in how we have approached this problem.

Confusing. I initially thought someone ported the Dagger DI framework to Python: https://dagger.dev/

I'm currently using Dagger and Anvil for my DI needs. It's been working really well, especially around what Anvil permits in terms of multibindings defined on the type declaration rather than in a module. For example:

Great job, I have been waiting for this feature/fix for a long time https://github.com/google/dagger/issues/2328
