In response to being downvoted — I would assume that tracking all of the records in function closures (first-class functions) would be a real headache, though slightly aided by the fact that garbage collection is available, and the question of whether to support eval raises a number of issues.

In any case, compiled Common Lisp is not something that resembles other compiled languages... and the purpose of my article is to discuss either designing an interpreter or a compiler, not a dynamic compiler, recompiler, or compiled code that requires some kind of runtime interpreter as a side, all of which are extraneous use cases for hackers not people learning how to program. They also make for poor pedagogical tools.
