I've not yet played with any of the h-f/function stuff in 3.5.

Can anyone give a quick explanation as to what they're for? For example, in
Gilles's post, why use a hf with the ridged mf rather than just using the ridged
mf directly?

I know, I know - I could read the docs and test things out, but I thought that a
discussion on this might be of general interest anyway.
