I'm not sure I understand the question, though I suspect I may know the answer. Could you be a bit more specific? I'm not sure what you mean by "optimized away so they won't show up on a call to eval". And what, spoecifically, are "lexical variables"? Variables that have scope determined lexically? -- hendrik _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
