It is much better to just wrap all the definitions in your .cpp file in:

namespace foo {
}

This is _especially_ true if the .cpp file is included.  Because, as
others have pointed out, using namespace has an effect over the entire
compilation unit after the declaration is seen.  This may cause people's
code to suddenly act differently and misbehave in strange and unusual
ways just because they included your header file.

Have fun (if at all possible),
