Well, after the countless posts in answer of mine, that's what we
could deduce :-)
So, let's go.
I looked at the function gnus-configure-posting-styles, and I realize
that I really don't want to touch it. To implement the thing, I'm
thinking, in a first approach, of a wrapper wich converts the tree in
a flat standard gnus-posting-styles, in short : for each leaf in the
tree, reached by a in-depth walk, we provide a boolean expression to
insert as a standard match the gnus-posting-styles, along with the
posting attributes of the leaf. This sounds undoubtfully familiar to
all the tree-algorithms-addicts we all are :-)
They're two drawbacks :
- the gnus-posting-style variable won't be human-readable, perhaps
should be hidden
- if the tree is complex, the leaf expressions could be very long, the
gnus-configure will slowly parses a very very big structure. I don't
think we will encounter such a situation, but who knows. If speed
matters, providing a global function which stores a walk-state in
the tree, and using this function in match-clause of
gnus-posting-styles should do the trick.
Comments?

That could be dealt with by adding an additional variable that this
complex spec would have control over, and letting
`gnus-configure-posting-styles' use that as well.

I think that might be a problem.
`gnus-configure-posting-styles' is a quite long function, but it
isn't all that complex. I think you should be able to shoe-horn in a
predicate-like spec in there without too much problem.
A third method would be to use `gnus-make-predicate' to just make a
function out of the predicates, but it might be difficult to make it
fit in there...
