| a nofork command substitution is
| '${' compound_list '}',
you omitted the extra char there, not that it matters for
the purpose here.
| The difference, as you say, is
| that a command substitution is allowed as part of a word,
Not "allowed as", always is, that's the only place it can appear.
It might be the whole part, a prefix part, a suffix part, or an
embedded part, but it is always a part of a word.
Of course, almost everything (or everything you'd imagine) in the shell
is a word, so this is not highly restrictive.
