By these two lines:

val input = Array(1,2,3,4,5).cl
val output = input.map( (i:Int) => 1).toArray

the compiler plugin generates the following error in the 2nd line. I use scalacl-0.2 with javacl-1.0.0-RC2.

[scalacl] Test.scala:36 transformed Array[Int].foreach into equivalent while loop.
[scalacl] Converted <<<
1

to <<<
(1)
