I have supported this idea in the past, and I've recently taken a look
at how it might be implemented.

Unfortunately, I don't currently see a way of doing it.  Unless the
@deffns in the manual are restructured in some big way, it means that
we'd need a @deffn command and one or more following @deffnx commands to
generate entries in different indices.  That appears to be not currently
possible, and I've not managed to find any indication that it's even on
Texinfo's radar.

I'm happy to keep looking at this if people have other ideas about it;
but at the moment I'm stuck.
