Julia's JIT is a simple plain method jit, the easy one. He doesn't describe the pro's and contra's of method jit vs tracing jit. In short, method jits explode in memory usage and forbid expensive optimizations. The advantages are of course as described easyness to work with, reproduce and debug. Most JITs start as simple method jit, and then advance to Tracing JITs. Esp. with performance orientated languages with a lot of vectorization potential.
It's a great language. But the JIT will be improved sooner or later. Esp. with the memory-expensive type-optimizations.
