Hi,

There is common need of getting value from optional with possibility to 
define default value in case of the optional is uninitialized. I suggest two 
alternatives:

    optional<int> o;
    int i = o.get(123); // meber function get with additional parameter
    int j = from_optional(o, 123); // free function

Both alternatives can be implemented simultaneously.

What do you think about it?

Regards,
Vaclav
