I may yet be disappointed but I'm expecting them to open source it after release as they do with the other LLVM changes they make.

I think it could work with anything based on C libraries (C++ linkage sounds a bit trickier) but it has been very much designed to operate with the Obj-C libraries.

It might be that Haskell is a language to learn and may help you develop functionally if you switch to Swift later. There isn't that much to learn about Swift itself really.
