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))

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