`:ls` gives weird output

[asm0dey]

Consider following example:

[4] fun String.lll() = 3
[5] :ls String
fun lll(): kotlin.Int

I would expect to see here anything but this. By "anything" I mean only "real" members of String or "real" + extension members.

At the moment this is by design. @khud, let's discuss what behavior we want to have here.
