the implicits for TupleConverter and TupleSetter can lead to subtle bugs at
times. i think its because of the low priority defaults for any generic

for example i ran into issue where an implicit wasn't propagated by
mistake, and it seemed to fall back on an incorrect generic choice without
any warning. it boils down to this:

scala> implicitly[TupleSetter[(String, String)]].apply(("ha", "ba")).size
res9: Int = 2

scala> def test[A] = implicitly[TupleSetter[A]]
test: [A]=> com.twitter.scalding.TupleSetter[A]

scala> test[(String, String)].apply(("ha", "ba")).size
res10: Int = 1

i wish definition of test had failed.
