String.format

Hi

In my Java live i often use String.format. However Scala seems to handle this method poorly, as can be seen in this example:

Welcome to Scala version 2.7.3final (Java HotSpot(TM) Server VM, Java 1.6.0_10).
Type in expressions to have them evaluated.
Type :help for more information.

scala> String.format("hi: %d",5)
<console>:5: error: type mismatch;
 found   : Int
 required: java.lang.Object
Note that implicit conversions are not applicable because they are ambiguous:
 both method int2Integer in object Predef of type (Int)java.lang.Integer
 and method intWrapper in object Predef of type (Int)scala.runtime.RichInt
 are possible conversion functions from Int to java.lang.Object
       String.format("hi: %d",5)
              ^

scala> String.format("hi: %d",5.asInstanceOf[Object])
res1: java.lang.String = hi: 5

Is this an oversight in the design of the language? The integer value does not really need any of the implicits, it should just be passed as is. I need to use asInstanceOf[Object] to force the compiler to realise this.

Thanks,
