You are welcome to use our [GDML connector](https://github.com/mipt-npm/gdml.kt). It uses a custom plugin to load dependencies, but I should not be a problem,

Schema from classes is also quite useful.

The GlobalScope is indeed a bad practice. The good practice is to create a scope for your application and pass it explicitly where you need it. Could you give links...

I don't understand what this line does. Looks like it just assigned a field to itself.

You probably wanted to link to something like https://github.com/scenerygraphics/scenery/blob/f6aedc19714d899b316235b53dc3d5c0b44bf83a/src/main/kotlin/graphics/scenery/DefaultNode.kt#L61 And it is indeed not good. If the process is long, the structured concurrency is broken here. You need to provide...

`0.8-rc` still has a lot of problems with documentation. For example it is not clear how generic is used here: https://github.com/Kotlin/dataframe/blob/db20e697fa40af068a4cf7155e7086349f12d14a/src/main/kotlin/org/jetbrains/kotlinx/dataframe/DataFrame.kt#L22

A little bit. But not fully. For example, it is not clear what variance of `T` is allowed in the schema. Should it be variant T or all descendants of...

It is a great idea, but it will be worth it only in terms of interop with other platforms. For JVM-only, Arrow will give nothing new.

I am not sure about the importance of the use case, but there is a problem with the syntax. Double bang (`!!`) is in most cases a synonym to code-smell...

@dzharkov It is problematic from the teaching perspective. We are teaching that double-bang must be avoided and should be used only under very specific conditions. But introducing another similar syntax...
