What is the order of function returned by val KClass<*>.memberFunctions: Collection<KFunction<*>> , is it the order of declaration?

[Ryan]

I wouldn’t make any assumptions here.

Probably at the whim of the compiler.

I know that at runtime one of the key performance advantages the JVM has over C is that the JVM gets to re-order fields according to a heuristic. And the implemention of Unsafe makes implications that this is done eagerly. So my guess is: you get them back in the order that the JVM thought would be fastest --effectively random.
