I would have prefered to not use joiner() but working with 
ranges of ranges of ranges (splitter() on each line) got a bit 
weird and confusing.

Ok, I guess it's not that weird after all:

void main() {
   size_t[string] dic;
   stdin.byLine
           .map!(l => l.splitter(' ')
                                   .filter!(w => !w.empty && w !in dic)
	   			   .map!(w => writeln(dic[w.idup] = dic.length, '\t', 
w)).eat).eat;
}
