Yes.

`and' is a special form, not a procedure.

The main reason why it isn't a procedure is that procedures get all
their arguments evaluated before they are applied, and `and' is often
used as a control structure (i.e. a kind of use akin to `if').  Only
those arguments that *have* to be evaluated in order to determine its
result are evaluated.
