Description
There are two (perhaps more) places in [exec] where fold-expression is used to expand the function: [exec.when.all] and [exec.snd.expos]:
[](auto&, auto&, auto&... ops) noexcept -> void {
(execution::start(ops), ...);
}
Do we need to convert the return result to void as LWG 3755 does to conform to the current best practice of the standard? Is this editorial, or does it require an LWG? Or maybe this is not necessary at all?

Research direction
Read the fold-expressions in [[exec.when.all]] and [[exec.snd.expos]], then compare their wording with LWG 3755. Determine whether the comma-expression result should be cast to void and whether the change is editorial or requires an LWG issue; done means the required resolution path is clear.
