It is nice to have a single path class, thank you. I'm curious about the internal path representation and the conversion to std::string or std::wstring. If I understood the logic, the string type and path traits are now function template parameters. Is that correct?
Could you please estimate when filesystem v3 will be included in a boost release?
Thanks again.
