Yes, but since the class which contains the constructor which has the 
argument which has the default is:

basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >

Then shouldn't npos be identified as:

std::basic_string<wchar_t, td::char_traits<wchar_t>, std::allocator<wchar_t>

instead of :

std::basic_string<_CharT, _Traits, _Alloc>::npos


In other words, shouldn't the type of npos be identified by the actual template parameter values used in declaring the template instance in which npos is being referenced, instead of by the variable names used in the template definition itself?
