The syntax is:
while_(conditional_expression) [ sequenced_statements ]
Example: This code decrements each element until it reaches zero and prints out the number at each step. A newline terminates the printout of each value.
std::for_each(c.begin(), c.end(), ( while_(arg1--) [ cout << arg1 << ", " ], cout << val("\n") ) );
