Weird REPL-only error message: value asInstanceOf does not take type parameters

[smarter]

The first error is legitimate, the second isn't:

scala> val a: scala.collection.Seq.Coll = Int 
1 |val a: scala.collection.Seq.Coll = Int
  |       ^^^^^^^^^^^^^^^^^^^^^^^^^
  |type Coll in class GenericCompanion cannot be accessed as a member of collection.Seq.type from module class rs$line$1$.
  | Access to protected type Coll not permitted because enclosing object rs$line$1
  | is not a subclass of class GenericCompanion in package generic where target is defined
1 |val a: scala.collection.Seq.Coll = Int
  |^
  |value asInstanceOf does not take type parameters
