Any other call must have all variables spilled first. You're concerned about the possibility of redefining Lisp functions defined in other files, and that the new function definitions might touch variables bound in your file. I think it is legitimate to compile assuming they don't do that. How about seeing where you can get, that way? > Given the discussed > suspect of poor performance I intentionally left this task aside to work > on more urgent tasks.
