818,No zero-argument in_place(),nobody,Fernando Cacciola,"{{{
There is no zero-argument version of boost::in_place(). I would have expected this to exist, and to be a factory for a type's default constructor.

This is necessary when attempting to use boost::optional with a type that is not CopyConstructible, or where the copy constructor is expensive:

    #include <boost/optional.hpp>
    #include <boost/utility/in_place_factory.hpp>

    boost::optional<my_type> my_optional;
    my_optional = boost::in_place();

I'm not aware of any other way to initialise a boost::optional to a default-constructed instance without unnecessary and perhaps impossible copying.
