Yep that's what I meant about namespaces. With the convention to
always have the ending comment, sounds important to me precisely
because of the lack of indentation.

Even if a struct and a class are technically the same, there's a
strong "emotional" difference between them in the head of most
programmers. "class" is often used for classes meant to produce actual
objects, which have methods and an active role in the runtime
functioning of the program. "struct" is rather used either for POD
structures, or for classes used at compile-time like metafunctions,
tags, traits, etc... So if the code above was mine I guess I'd choose
"class", but I'm open to use "struct" if you really prefer.

No strong opinion about that so it's ok for me. About "typename", even
though I often use "class" just by convenience (it's shorter ;-)), I
think you're right with "typename" because historically, the fact that
"class" can be used that way is an accident.
