Out of interest, what would:
auto str = boost::convert<std::string>::from(123);
Do? If boost::convert stores by pointer/reference, it would be quite dangerous.
str would be a boost::convert<std::string>::converter, not a std::string as one would probably expect.
I think making libraries 'auto safe' is a good idea, I expect to see auto usage shoot up very quickly, and libraries should do their best to work well with auto.
This may be one of the most compelling arguments against the current interface.
Agreed. I know I'll be jumping on the bandwagon as soon as auto becomes mainstream in my two main compilers, MSVC and GCC. So this is a compelling argument. But would it even be possible to keep the "smart result" (either convert<>::result or optional<>) and auto compatibility? If (as I suspect) not, this would seem to necessitate different syntax for value/throw and functor. -Matt
