The most interesting thing Adobe has recently announced at Adobe MAX is (easily) Alchemy. It adds some modest support for C/C++ in Flash, but this is still nothing compared to how they did it. Tucked away in the Alchemy FAQ it mentions they used LLVM to do the job. It works by compiling C/C++ to the LLVM instruction set and then converting that to Flash bytecode.
LLVM is intended to act as a medium between a language and an instruction set. If you write a language that compiles to LLVM instructions, you automatically support any instruction set that LLVM supports. If you write a back-end that can understand/convert LLVM instructions, you support any language that compiles to LLVM instructions.
So basically, Adobe may have just opened the door for Python, Java, CIL/.NET languages, and others. I doubt they work right now (I haven’t had the opportunity to try Alchemy yet), and support for Flash’s API would be missing of course, but it appears to be coming.
