Combining Arrays in Scala

If I have DerivedType1:BaseType and DerivedType2:BaseType and Array[DerivedType1] and Array[DerivedType2], what's the most succinct way of combining them into Array[BaseType]?

Use the ++ method on Array.

scala> class A; class B extends A; class C extends A
defined class A
defined class B
defined class C

scala> Array(new B, new B) ++ Array(new C, new C)
res33: Array[A] = Array(B@b7501b, B@ec5359, C@1540d0c, C@124a927)
