Better? or less good?

Dear Racket users,
I noticed that Racket detects the variables used without any
value. But let us consider the expression:
(or #t Gor)
Since "or" evaluates as few arguments as possible, the result is
#t, but this expression is rejected by Racket because "Gor" is
unbound. So the rule would become: some arguments of "and" and "or"
may be not evaluated, for example:
(and #f (/ 0))
but do not use this feature with unbound identifiers... From my modest
point of view, that is not homogeneous... What do you think, please?
Cheers,
J.-M. Hufflen
