Put me in with Jeff on this.  
If the past were otherwise, I would have functor(X, f, 0), !,X == f() so that
all predicate calls use the ().  If you make the code so that in most all cases 
f() and f behave the same that might be okay as well, but it's a recipe for 
confusion when there's different meanings depending on the syntax.  

But my main argument is not about breakage or uselessness.  I'm prepared to fix 
broken code and actually use new features.  But I find the features are confusing
when you try to do the advanced meta-stuff that Prolog is supposed to be good at.
What about code like this:

invoke(Map, Pred, Args, Result) :-
   F =.. [Pred|Args],
   Result = Map.F.

Apparently nothing of the sort is possible.
