It's just an exception rather than a rule.

If you compile the code, the byte-compiler will give you a warning suggesting to replace with-current-buffer for save-excursion + set-buffer. >> - should not `setq` on a global variable that doesn't have an appropriate >> namespace prefix. >> > Do you mean the following is not allowed: > > (setq apple 'banana) > > but the following code is allowed: > > (setq dmp-apple 'banana) Neither are recommended without first declaring that global variable (since that's what it is: a global variable). And global declarations need to use a proper namespace prefix. Otherwise you're at risk of stepping on someone else's toes/variables. Stefan
