Can I do a double "." ?

struct iterator{

   struct first_leg {
     iterator& it_;
     first_leg(const iterator& it) : it_(it) {}
     Range operator.(const iterator &end) { return Range(it_, end); };
   }

   first_leg operator.() { return first_leg(*this); }
}

iterator a = c.begin();
iterator b = c.end()
Range x = a..b; // dot operator twice ?

for ( auto i : x ) {
// code...
}

BR
Cleiton

If you're talking about Stroustrup's operator-dot proposal, no; `..` would
still be syntactic nonsense. The proposed `operator.` doesn't really
override the use of the `.` grammar. It overrides essentially *all*
operations that would access that type through a variable or reference to
an object.
