One way to look at the anonymous namespace is to consider it a namespace with a cryptic name. That name is only known within the current compilation unit. Thus anything declared within the namespace can't been seen elsewhere because the namespace name is unknown. So I could write namespace { int n; } and n would only be visible within the current compilation unit whereas int n; would be globally visible. -- Ian Collins -- end of forwarded message --
