> Making compilers slow and complex doesn't mix well with JIT compilation. Funny, I was just thinking the opposite: Compiler-driven parallelism loses against CPU-driven parallelism because the CPU has live profiling. With a JIT the compiler can have it too. The debugging problem on the machine-code level becomes less of an issue when most people write higher-level code too.
