Please see the following code:

trait T {
  type Representation
}

type A<Value: T> {
  var value: Value.Representation
}

extension A<Value: T> where Value.Representation: Movable {}

The code fails to compile with the following error:

/Users/lucteo/work/hylo/hylo/Sources/FrontEnd/TypeChecking/TypeChecker.swift:3273: Fatal error: not implemented
make: *** [bug] Trace/BPT trap: 5
