There's a Steve Yegge rant on that topic. It would be much easier to add first class support to a language if its implementation exported the internal data it creates from running/compiling the programs. Without it, we are left with hacks, or lots of work for every new language, like Eclipse, which Yegge says has 3 Java compilers inside.
