Scala is deprecating the use of adaptation from n-args to tuple, so for example you need to use:

val x: Option[(Int, Int)] = Some((1,2))

This is to remove some ambiguities that can lead to non-expected result in some case.

I'm not sure I really like the result. In some caes, the alternative tuple notation works very well, but not always:

... myLiftXmlElement % (("class", "error"))  // bof

... myLiftXmlElement % ("class" -> "error")) // nice!

But in all case, we should have the smallest number of warnings (ideally, 0) with -Xlint option enabled.
