Honestly, I would rather have a speedy runtime and put the effort into a static analysis mode built into PHP. The stated goal of so many who push the strict types everywhere argument is that it helps find bugs. So let's have an analyze mode that finds these bugs without bogging down the runtime with thousands of type checks. -Rasmus
