08/07/2019, 10:38 AMHow would a higher-order function in a companion object variable act when being called by multiple threads?
Will Kotlin run the function in the caller thread or are objects somehow shared across threads?
I need a provided for a thread's namespace and it would be much cleaner to have that provider be a higher-order companion object function but I'm unsure whether it will correctly call the provider from the thread

08/07/2019, 10:39 AMObjects are singletons, across threads. Calling a function makes it execute in the caller's thread. Companion objects are not relevant here at all
