Yes, is seems that it comes down to personal preference. Dave likes to say
filesystem, and you don't like fs. Out of curiosity, do you like 'std'?

The reason I prefer short namespace names (and I'm very glad that the
committee decided to place the library in 'std' and not 'standard' or
'standard_library') is because I want to keep my identifiers fully
qualified, if possible. However I apparently lack the mental discipline
required to repeatedly type boost::filesystem::directory_iterator,
std::string::size_type, std::string::npos, or std::vector<X>::size_type
(much less like it :-) ).

I believe that there is a (subjective) threshold that shouldn't be crossed,
or the programmer just "goes unqualified". Now, it's well known that many
programmers don't tolerate namespaces at all. Others, apparently, are
content with longer namespace names if this aids clarity. But I somewhat
suspect that the majority are like me, they'll keep using qualified names
until the library offers them an excuse to cut corners. So I'd rather not
give them that excuse.

Just my opinion, of course. :-)
