This is a great achievement: bitwise-identical output of the compiler when bootstrapped with different CL implementations. It is inspiring to see people like Christophe Rhodes work on SBCL and make tremendous progress. He is sufficiently honest to write how he missed an obvious typo (guess what, this happens with every language, no matter how hard you try to avoid them). Unfortunately, this is now the most discussed part of the article, which is sad.
