Tuples and Double are there in the HEAD build now -- but we're still
thinking about how best to treat Ptr, which is essentially
un-marshalable.

| Any chance of Data instances for tuples of size
| greater than 2... One of the nice things about generics is
| you can use them by deriving Data on your datatypes - of
| course this doesn't work if you all of a sudden have to
| put a load of boiler-plate in just to use tuples...
