is

@Throws

annotation worth anything in practise?

for interop with java, if you want to signify checked exception when calling code from java

oh, didnt know that, thanks

it's required for interface methods backed by java.lang.reflect.Proxy to throw checked exceptions even if the consumer is in Kotlin

If you write a Kotlin interface that a checked exception to be thrown by one of its abstract methods, and then a Java consumer implements that interface, they can't throw the exception unless you add

@Throws

(because their override of that method can't add

throws

to its header)
