Seq.empty[T] vs. Nil?

[Willis Blackburn]

Does anyone use Seq.empty[T]? Nil always seems to fit the bill and is shorter.

Sometimes you need to add a type to your Seq or List for the Inferer
and in this case
Nil doesn't cut it as it always uses Nothing as the type.

Hi,

I prefer
var ns = Seq.empty[Int]

to
var ns: Seq[Int] = Nil

The type hint is required in the second case so the compiler don't infer
"List[Nothing]" (from which "Nil" extends).

Germán
