Documentation inconsistency about exceptions

[kuznetsss]

Hi, thanks for the useful library!

I think there are a few inconsistencies about whether function or method throws an exception: value::as_string():

parse()

In both cases it says in the description that exception could be thrown but at the same time it says Exception Safety: strongly guarantee.

"Strong guarantee" means that if the function throws an exception, then any of its arguments, including the object on which the function is called (if it's a member function) aren't changed. You are thinking of the no-throw guarantee.

See this document for more info: https://www.boost.org/community/exception_safety.html (section 3 discusses exception safety guarantees).
