So it doesn't like inlining and type specializing, preferring heavy factoring and run-time dispatch instead. Analysing the productivity of these trade-offs is notoriously tricky because there are lots of interdependent variables. So the heuristics for inlining and type specialization are suspiciously subjective. Hence, the current approach is just being cautious. I've considered writing a whole program optimiser to do things like type specialization and inlining but in most cases it wouldn't buy you much. It some it could buy you a few times better performance though...
