Hi,

with optional<T> being part of the standard library, are there any plans to 
make use of it in standard library components? One specific example that I 
am thinking of is to deprecate the std::basic_string::find* functions that 
return npos when nothing is found, and replace them with functions 
returning optional<size_t>.

Best wishes,
  Jens
