#include <boost/phoenix/statement/if.hpp>
The syntax is
if_(conditional_expression) [ sequenced_statements ] .else_ [ sequenced_statements ]
          Take note that else has a
          leading dot and a trailing underscore: .else_
        
          Example: This code prints out all the elements and appends " > 5", "
          == 5" or " < 5"
          depending on the element's actual value:
        
std::for_each(c.begin(), c.end(), if_(arg1 > 5) [ cout << arg1 << " > 5\n" ] .else_ [ if_(arg1 == 5) [ cout << arg1 << " == 5\n" ] .else_ [ cout << arg1 << " < 5\n" ] ] );
          Notice how the if_else_
          statement is nested.
