Thanks, that's really useful information. So even doing (require
'message) in nnimap.el wouldn't allow us to benefit from the
eval-when-compile load of subr-x in message.el.

Besides message.el, nnimap.el is the only gnus lib to use when-let*. I
can just add another subr-x require in nnimap for now -- if it starts
getting used in more places, I guess we can require subr-x
unconditionally in gnus.el.

Thanks,
Eric
