It is a common idiom even in GLib that callbacks receive two anonymous

There's a lot of retarged garbage in Glib, just look at their lists.
If someone smarter wrote Glib, we would not need struct list_head.
I use both list types, because there's a use case for both. You don't
always have the luxury of having a struct in which to embed data+next
pointers. Allocated strings are an excellent example.
GFunc has two parameters for a reason :) See for example
http://library.gnome.org/devel/glib/stable/glib-Doubly-Linked-Lists.html#g-list-foreach
It really is a common idiom, based on a common need, not just my style
preference. :)
