John, thanks for elaborating on the differences between c and c++ concerning namespaces.

I also prefer the namespace name to be GnuCash in full. I don't have a strong preference 
regarding snake vs. camel either.

Apparently lots of schemes exist.
boost uses underscores.

Qt uses camel and goes even further: class types start with a capital letter and each word is 
capitalized,  while for member functions each word is capitalized except for the first one.

I also found the naming rules for Google which is a mixture of both:

The latter takes more discipline while coding. On the other hand it helps distinguish what a 
word means. Is it a variable, a type a function ? The style it's written in helps distinguish in this 

Personally I like such a scheme.
