...which cuts both ways, as you need to first look for the function's 
definition to see what it does exactly, compared to having it inline at 
the point of use (and will become more moot with C++11 lambdas).

That's IMO a reason why in C++03 a for loop with a short body can be 
overall preferable to a for_each that requires a one-off function 
definition.
