Hi there :slightly_smiling_face: 
why does Kotlin need `Array` in the first place? Why not use `Collection` and let the compiler optimize them away as JVM Arrays where possible?

not sure I got what you said, sorry. 

The concept of :java: Arrays could be expressed by a :kotlin: Collection and the :kotlin: compiler could provide the necessary magic. 

And `ArrayList` is a :java: class, not a :kotlin: class, so I'm not sure why that would be relevant.
