Point taken about Lisk and Liskell. But I think that that is, as you say, cherry picking features, not actually merging the philosophies of the two languages.

As for the same starting point, both had their origins in academic programming language research. It's true they don't have a direct common ancestor, but the point I was making was that their creators were aware of the issues, and chose very different directions as solutions to basically the same problem.
