I would say that it's completely fine as long as: - It's in an implementation file and - The utility has not dependencies other than the standard library The first ensures that namespace pollution is localised. The latter limits you to cases where there is no chance of there being any conflicts (if you're defining a symbol in a program that has the same name as an STL one then you should probably be referring to it by its fully qualified name anyway or the code will be unreadable).
