unnamed namespace,

[vsgdp]

I just want to clarify: Say I have a helper class that is only used in one
translation file (e.g., a predicate class). I don't want the name of this
class to conflict with other class names in other files, so I put it in a
nameless namespace?

That's one very important use for unnamed namespaces, yes. Generally,
anything you think of putting in the global scope (or any other scope
that transcends a single translation unit), but don't want to be easily
visible in another translation unit, or potentially conflict with some
other name, belongs in unnamed namespace.
