Using varargs from Scala

def foo(msf: String, o: AnyRef, os: AnyRef*) = 
  println( String.format(msf, (o :: os.toList).toArray : _* ))

def foo(msf: String, o: AnyRef, os: AnyRef*) =
  println( String.format(msf, o :: os.toList : _* ) )

or

def foo(msf: String, o: AnyRef, os: AnyRef*) =
      println( msf format (o :: os.toList : _* ) )

I much prefer the latter, though it has no locale* support.

  • Scala 2.8 does have locale support with RichString's format.
