In "Block Statement", (http://tinyurl.com/b25hr) you show how to use the 
comma operator to sequence statements. I see problems here, especially 
when calling a function that takes a predicate that isn't the last 
argument. For instance, how would you use Phoenix to create a 
filter_iterator?

   iterator begin, end;
   ...
   boost::make_filter_iterator(arg1 > 5, begin, end);
   // Oops! ---------------------------^

Isn't that comma going to be Phoenix's overloaded comma?
