Just-in-Time compilers... we've all heard of them! What are they really? Why would anyone want them, are they actually a good idea, and how do they fit in with C++ since we all use Ahead-of-Time compilers compilers. I’ll illustrate how our view of compilers is really monolithic, and how compilers through time, and still today, are actually a continuum.  Is
