Unfortunately I didn't quite understand what you ment.
Partial evaluation I learnt from the links given in the Tunes Learning 
Lounge (thanks Martin), pure function I guess it's that it will be
like in functional programming, but I don't know what continuation is...

I also read in Tunes' site that you will be trading with objects...
so where does that leave us?
Would you mind giving some example.
Thank you very much for you time.
