[Boost-users] Converting tuples

Hi, I have a function that is templated with a tuple. I would like to convert the input tuple to a different tuple with the same size, and with related but different types. I can have any number of items in the tuple, not just two as given in the example. ie tuple r = GetProperties>(); The template magic that will achive this currently eludes me. How can I do this? Thanks. -- Orhun Birsoy
