Ah, yes. Mantissa. That's been in the works for quite a while now. Hope it lives up to expectations. I wonder if it implements a "just in time" compiler simiilar to IBM's JAVA implementation. What might be even better would be something like how the "i" (AS/400 offspring) does it. Compiling Java to byte code ends up with a byte code file with an associated "shadow" file which is actually native Power code. A bytecode compile-to-native would be an interesting piece of software. As would something which could "compile" x86 instructions into z/Arch instructions. And I am aware of the problem of "is this code or data?" .So something like the "just in time" compiler, but which could save the "compiled" object across runs would be _very_ interesting, but likely not really very useful, due to recompilation and so on.
