Hmmm, actually in zsh, there is parsing going on there:

$ zsh -c 'f() { echo $(for); }; typeset -f f'
zsh: parse error near `)'
zsh:1: parse error near `$(for); }; typeset -...'

But still, the comments appear not to be discarded at that point:

$ zsh -c $'f() { echo $(echo x # comment\n); }; typeset -f f; f'
f () {
        echo $(echo x # comment
)
}
x
