So in Kotlin 1.0 I was getting a runtime error on some code. Here is a stripped down version of my code that still demonstrates the problem:
private fun foo()
return arrayOf(1, 2)
This failed at runtime saying it could not cast the array to java.lang.Void, but it gave a stack trace line number that did not exist so I had no idea where the actual error was.
To try to diagnose it I tried switching to 1.0.2 eap and it fails at compile time with:
'Nothing' return type needs to be specified explicitly
The line number is on the blank line before the function and the message was not very helpful but I was able to deduce that the error was due to the return statement. If I remove the return and just have the expression as the last line it works.
So I know the fix, just looking for some pointers to documentation on the thinking here regarding return statements inside of lambdas and is this a bug?
