There are Forth systems that can do this as well. You have to manage everything yourself and your code might not work or be compiled to native code on other systems, but this is true of everything else in Forth.
Erlang also has hot code loading with versioned code and precise and easy ways to migrate processes from old to newer code, and with HIPE you get native code (but not compact executables) on some architectures. The presentation's interesting, but the title only furthers the non-goal of making people talk about Common Lisp.
