Note that in our implementation the body of `delay', etc, can have
multiple expressions with an implicit begin. While this is not in the
srfi, you're effectively closing off this as a future extension. More
than that, if you go with the above, then you should probably consider
also making your `delay' and the rest work in the same way with
multiple subforms = multiple values, to maintain a uniform interface
where `eager' and `delay' have the same interface.
(And yes, IMO, this kind of extension is not too great since it breaks
this uniformity anyway.)
