There is a special function; you can use

for_each(a.begin(), a.end(), std::cout << constant("blups:") << _1 << constant(' '));

to defer evaluation of the insertion operators until the lambda function is invoked. (You don't need the second 'constant' really; it will be deduced.)

There is also a 'var' function for deferring modifiable variables.
