My understanding is that Scala already wraps lambdas in internal class instances with a `call` method, so I would imagine that CPS will carry a similar performance and memory hit. It certainly won't be quite as fast as idiomatic Java code, but it should be considerably faster than other non-local exit implementations that rely on exception handling to manipulate the stack.
