has anybody got a functional use case for

mapTo

using maps?

Copy code

val source = HashMap<String, Double>();
val sink = HashMap<String, Double>()

source.mapTo(sink.entries){ x -> x }

is a no compile because

sink.entries

MutableSet<MutableEntry<String, Double>>

and its expecting

MutableCollection<Map.Entry<String, Double>>
