And C++ belongs to the C language family, but one could still say something like "the next great thing would come from a C rather than a C++ like language" (I'm not judging if this is true here, just that it's quite clear what it means).
Yes, that's close! I also think that we'll need a better treatment of effects than either ML or Haskell can give us, but I hope to have something that has been carefully thought about, rather than bolted on like Haskell's effects.
It sounds like call-by-push-value gives a nice unifying approach to CBN/CBV and also effects. I am hoping that something interesting will come out of that work.
Frank's basically based on an extension of the CBPV calculus. As far as I know, Conor's also working on extending the core Frank calculus to the dependently-typed case, though this might take a bit.
