[Boost-users] [mpl] SourceClass --> DestClass mapping

Hello,
 
This is kind of newbie question. Any help would be greatly appreciated :).
 
I'd like to map (SourceClass_i) list to (DestClass_i) list in the way that for any instance of SourceClass_i passed to the mapping expression, an instance of DestClass_i will be created and the result of the expression would be of type DestClass_i.
 
I defined the mapping as follows:
 
typedef mpl::map< mpl::pair<SourceClass1, DestClass1>,  mpl::pair<SourceClass2, DestClass2> //, etc...> source2dest;
 
Now I guess I have to take the result of mpl::at<source2dest, SourceClass> and apply kind of:
 
template<typename DestClass> struct Creator{   static DestClass create()  {     return *new DestClass;   } }; 
...but unfortunately the things don't come together.
 
Thank you in advance!
