[GitHub] [kafka] vvcephei commented on pull request #5539: Fix Streams Scala foreach recursive call

["vvcephei (GitHub)" <gi...@apache.org>]

Technically, this is a public interface change, and would require a KIP.

Note that we don't really need the implicit; it just makes the internal implementation nicer. You could instead do:
```scala
def foreach(action: (K, V) => Unit): Unit =
    inner.foreach(new ForeachAction[K, V] {
      override def apply(key: K, value: V): Unit = action(key, value)
    })
```

right?
