Is there a difference in Scala between Seq[T] and T*?

Question

My IDE's tooling shows that xs has type Int* in the following snippet:

def accept(xs: Int*) = true

The language reference, however, says that a repeated parameter declared as T* has type Seq[T]. Is there a difference between Int* and Seq[Int]?

Answer 1

They are different, and it's somewhere between bug and regrettable feature that T* leaks into type signatures.

Repeated parameter typed as T* rather than Seq[T]

Answer 2

Yes, they are different. See, e.g., Overriding a repeated class parameter in Scala?
