   void (x) { x->first < 0; }

for a void return? 
or

   (x) { x ->first < 0; }

And does a lack of a type denote a "auto" type? and if I specify one it over rides it?

   bool (classT * x) { x->first < 0; }

and with concepts do I have to specify the concept it satisfies as well?

   bool concept(pointerType(x),LessThanComparable(??::first)) (x) { x->first > 0; }

So how do I specify the type of "x" to the concept stuff for concept checking?
