Thank you, Dan.
Just a comment, to justify the awkward-looking MWE a bit: I have a book of exercises (it is an Inquiry-based intro to proofs class). The first edition had \item for exercises. But I want that I can make the number of exercises greater or lesser by omitting some (some instructors teach 3 credit classes, some teach 4, etc.). So I thought to have an optional argument to each exercise. For instance, because of the class option this sets \booklength to 1 and threrefore would not print the sketched-in exercise, since 2>1.
Prove each of the following exercises.
Prove the Twin Primes Conjecture.
-- more exercises--
I can't use \item because I can't say \item. In addition, when an exercise isn't printed, I want to copy it and its answer verbatim to otherproblems.tex for the instructor to use for extras. So I thought that verbatim copying required me to use environments.
I got it to work but for the one case that there is not text where it says "Prove each of the following exercises." But I absolutely get your point about groups. maybe it just won't go there.

"Not always," said Stephen.
