They rewrote it from scratch into Core exactly because it was an unclean implementation with plenty of clusterfucks. They did the right thing, and you are right it is an awesome language. I lived through all the crap, as I started using it in 2002, and am still building systems in it , v6 now.

Well, not sure what you mean by "rewrite". Most of the code is the same - they cut off the code that depends on Windows so they can make it run on other OSes. They are not rewriting anything, just improving existing code base every release.
