Nit: You don't strictly need the anonymous namespace here, as constants
automatically get internal linkage.

[Peter Beverloo, 2015/03/12 21:09:52]

Do they have internal linkage unless they've been declared as being exported,
like command line flags?

Having constants such as this in an anonymous namespace is far more common,
though, according to codesearch. Happy to change it if you feel strongly.

[Bernhard Bauer, 2015/03/13 12:27:19]

Exactly. (This allows you to declare a constant in a header, without violating
the ODR.)
It is, because very few people seem to know about this :) And TBH, a large
reason why I always point this out is to increase awareness. I think it allows
removing a couple of lines of code, so I personally prefer leaving out the
anonymous namespace, but I don't have a strong opinion.
