A modern programming language that makes developers happier.

kotlinlang

Other nice thing I would suggest:

Allow to actual implement a header with a default implementation. A possible use case is this one:
```
header fun ByteArray.copyRangeTo(srcPos: Int, dst: ByteArray, dstPos: Int, count: Int) {
	for (n in 0 until count) dst[dstPos + n] = this[srcPos + n]
}
```

Here I provide a generic implementation, that can be improved using System.arraycopy in JVM or the former for JS typed arrays, but as an optimization, not mandatory. So for example I wouldn’t have to implement for Konan at the very beginning and implement it later when optimizing things

Interesting idea! Please report it as a feature request at <http://kotl.in/issue|kotl.in/issue>

Sorry. Didn’t notice this (I still have issues with slack notifications)

I have created the issue already!
