The dots are important, because BODY normally implies one single form.
We are somewhat abusing notation by using `BODY...' to denote one or
more forms, but the convention is well-established and easy to grasp,
and there are no better alternatives.

I suggest doing everywhere what the `progn' documentation does, and
refer to BODY as "BODY forms".

  (progn BODY...)

  Eval BODY forms sequentially and return value of last one.
