True. One advantage the compiler[1] has is that it has the entire source 
code in front of it when it compiles. So it can check that everywhere an 
index gets called, the value is within range, for example.

But yes, obviously if the compiler could prove *everything*, there 
wouldn't be a 4% slow-down with the compiler adding the checks. :-)

  Ever notice how people in a zombie movie never already know how to
  kill zombies? Ask 100 random people in America how to kill someone
  who has reanimated from the dead in a secret viral weapons lab,
  and how many do you think already know you need a head-shot?
