- * Install custom unhandled exception hook. Returns old hook, or null if it was not specified.
- * Hook is invoked whenever there's uncaught exception reaching boundaries of the Kotlin world,

- * Hook must be a frozen lambda, so that it could be called from any thread/worker.

+ * The hook is in full control of how to process an unhandled exception and proceed further.
+ * For hooks that terminate an application, it is recommended to use [terminateWithUnhandledException] to
+ * be consistent with a default behaviour when no hooks are set.
+ *
+ * Set or default hook is also invoked by [processUnhandledException].
+ * With the legacy MM the hook must be a frozen lambda so that it could be called from any thread/worker.
