EmptyWeakMap

@ExperimentalWeakApi
fun <K, V : Any> EmptyWeakMap(): WeakMap<K, V>

A WeakMap implementation that immediately frees its elements.

Values passed to set are never stored, so the map is always empty.

Use this implementation when testing algorithms that use a weak map, to ensure they don't rely on the value still existing.
