Serialization opt-in syntax (again)

[Zakharov, Vladimir]

Excellent question. What is the cost and under what circumstances will it be incurred? I suspect, based on our experience with GS Collections, where all interfaces extend Serializable (including Predicates, Functions, etc.), the practical cost would be negligible.

And AFAIK, having all lambdas be serializable and having no lambdas be serializable are still not considered viable. So we're really in a tough spot.

Actually, given the horrors we're discussing here, let's be sure about this.  If all lambdas were serializable it would be a get out of jail free card for this design conundrum, so I must ask:  are we all satisfied that we have accurately quantified just how bad it would be performance-wise?  If so: how bad?
