Re: [boost] Is there any interest in a casting library where you don't need to specify a type of receiver?

3. I found this one today:
template<class T>
    operator T &() const
        throw(typename ::boost::disable_if< ::boost::is_same<T, MyClass 
const> >::type *)
You've solved the millenium problem! :-)
gcc3.4.5 and 4.1.2 seem to work fine.
Thanks!
Right, here is the new problem: If you specify at least one throw type 
(we do) then you have to specify all possible exceptions for the function!

    template<class T>
    operator T &() const
        throw(typename ::boost::disable_if< ::boost::is_same<T, MyClass const> >::type *)
        throw(::std::exception)
        throw(::MyLibrary::exception)
        throw( what else? )
