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?
