Of interest to Computer Go programmers: the addition of blocks to C,
which allow closures and other fun stuff, much like Lisp. LLVM,
which allows JIT compilation to multiple architectures, including
GPUs; Grand Central Dispatch, which provides very light-weight
concurrency; and CLANG, a new compiler which is said to be quite an
improvement over GCC. Open CL, which leverages LLVM to program GPUs.
Seems interesting indeed. Does anyone know how Objective-C 2.0
compares in speed to C? I like the promise of abstracting the CPU to
the point where you can execute either on the CPU or the GPU,
depending on which is available and which is suitable. I also like the
blocks, it seems a little more elegant and more flexible than
anonymous functions in Java. Combined with light-weight concurrency
makes for an interesting combination.
