I'm using it because I was looking for something to detect emptiness
and have found a macro in the preprocessor library. I can tell you what
makes me thinking that this is a public macro - it's name, which follows
the same convention as all the other macros' names in the library.

Now I understood that my impression was wrong.
May be it makes sense to have different prefix for private macros?
