"Only new one use the k-style, and as far as I understand, this may even be used only for private stuff."
I've long thought that using kConstant styling was for private API, whereas public API used B_SOME_CONSTANT.
I believe public macros could be M_SOME_MACRO, or merely take the form of a function... (as Be did in some cases).
I enjoy being able to fast-read code using the BeOS API, I can scan quickly scan for the constants and find my place easily, all lower-case or even functionsLikeThis() make it hard for me to find my place.
No idea why people DislikeCamelCase(). I, for one, AbsolutelyPreferIt() overThis();
