Yes, I found that to be by far the best solution, as '$ 1' makes it
clear that it's the Awk '$1' rather than the M4 '$1'.
The $[1], [$]1, and $[]1 solutions are used when you're trying to
quote the m4 '$1', and they work for Awk too, but it might confuse the
reader into thinking that another level of M4 quoting might be
involved. (The @S|@1 solution is too ugly for words, of course.)
