Scala: Why can't a method have multiple vararg arguments?

Can someone tell me why this restriction exists? Is this related to the JVM or the Scala compiler?

$ scala
Welcome to Scala version 2.10.4 (Java HotSpot(TM) 64-Bit Server VM, Java 1.7.0_79).
Type in expressions to have them evaluated.

scala> def toText(ints: Int*, strings: String*) = ints.mkString("") + strings.mkString("")
<console>:7: error: *-parameter must come last
       def toText(ints: Int*, strings: String*) = ints.mkString("") + strings.mkString("")

Scala is based on the Java virtual machine, which is configured to accept varargs only as the last argument, only one argument for each method. This does not work, so the compiler works.

To imagine this in perspective, imagine this method signature:

someMethod(strings1: String*, strings2: String*)

Let's say you skip 4 separate lines when called. The compiler does not know which String object vararg belongs to.

Scala varargs, ( ):

scala> def toText(ints: Int*)(strings: String*) = 
         ints.mkString("") + strings.mkString("")

scala> toText(1,2,3)("a", "b")

res0: String = 123ab
