Is there a way to reference an extension function ...

Is there a way to reference an extension function by package?
My issue: I want to expect an extension function that is available on some targets and not on others.

E.g.: File.readBytes():ByteArray is defined in jvm but not on native. So I want to have an actual expression that references the existing extension function (located in <http://kotlin.io|kotlin.io> ) for jvm and roll my own implementation for native targets.

So you're trying to write actual File.readBytes() extension and can't call readBytes from <http://kotlin.io|kotlin.io>, because it is now shadowed by your extensions?
In this case you can import readBytes with alias, and call it by the new alias then:

import kotlin.io.readBytes as kotlinReadBytes

fun File.readBytes(...) = this.kotlinReadBytes(...)

That does the trick, thank you very much!
