Problem is, that there is nothing like algorithms library currently in the boost.
Once, the other libraries will be reviewed, some reordering can be performed.
It is hard to make a border between two countries, when there only one.

all() predicate was added to the string_algo library, because, there was
a request to handle classification of a string. (i.e a sequence variant of
std::isspace and etc). all() with a set of classification predicated was a natural
choice for this task.
