Common lisp: macro vs functions (for beginners)

[@xabixps]

I think you have an error in the conditional, instead of
`(if ,(first exprs)
,(first exprs)
(my-and ,@(rest exprs)))
is
`(if ,(first exprs)
(my-and ,@(rest exprs))
,(first exprs))

[@the-lisper]

Yes! You are right! I should do more TDD to avoid this kind of mistake!

[@leandrohernandez386]

my-and or my-or. I think that the behavior of the macro seems more like an OR. Makes sense?

[@the-lisper]

Yes, it is, it was an oversight of mine!
