Is it ever ok to use runBlocking in regular code? Somehow that seems wrong

on a thread that doesn't belong to a Dispatcher, sure

What if that code is run on the Main thread?

(I'm asking because we have a library that does this. It just seems dangerous)

you should know the answer of whether the main thread is ok to block or not regardless of `runBlocking` e.g. UI main thread blocking bad, console main thread blocking (generally) ok

One example where it's ok

I want to use java.util.stream:
`myList.stream()
  .parallel()
  .map { runBlocking { ... } }`

why not `myList.map { async { ... } }.awaitAll()` which handles cancellation better

Yep, your version is better. Thanks.

It doesn't feel natural for complicated pipelines though, but I guess that's fine

I'm curious what is your use case for parallel stream, because it may require a but different code, depending on cass
