I don't think it is, The::playlistModel is just the name of the
instance function. There is no Playlist::Model::instance. The "The"
namespace is just a more pretty way to do it.

Sometimes they are aliases, but thats from people (myself included)
not knowing how to get the friending right.

Suppose I hadn't thought of that all the way through. :D

In my defense, sometimes singletons are only created explicitly,
though I don't know if we do that in our current code.

Anyways everyone knows the bike shed is supposed to be green.
