The definition for PROG2(1) says -

"prog2 evaluates first-form, then second-form, and then forms, yielding
as its only value the primary value yielded by /first-form/."

(Emphasis mine)

Shouldn't PROG2 be returning the primary value returned by second-form?

Thanks,

Chaitanya

Yes.  There appears to be a small typo here.

Who among us hasn't had fencepost errors and off-by-one bugs?

Thanks! I was worried I had grossly misunderstood the description somehow.
