When I run this program: (define atom? (lambda (arg1) (and (not (pair? arg1)) (not (null? arg1))))) (define and 'dummy) It highlights the `and` in the `(define and ‘dummy)`, and gives me this error message: define: expected a variable name, or a function name and its variables (in parentheses), but found a keyword
Do you not get an error message like that? If you don’t it looks like a bug. Or could there possibly be some setting that turns off error messages or something?
