[Boost-users] Using Boost Tuple Library instead of variadic macros

Hi,

I am trying to use the Tuple library in order to provide a logging interface which can get
a variable number of parameters and handle them in a type-safe manner.

However, though constructing a tuple by make_tuple seems easy enough (from a logging's user point of view)
implementation wise, I am not sure how to actually iterate on the make_tuple_mapper which is being provided to my logging method, as
generically getting the length and using invoking "get" on it does not work due to compile-time reasons (and there are no iterators available).

I am sure it must be possible to do it somehow, or else the ostream serialisation capabilities would not have been possible to implement,
but I guess I am just not sophisticated enough to fully grasp the MP intricacies...

My logging method currently looks like that:

template<class TheTuple>
inline void logTuple(TheTuple theTuple)
{
}

which might not be the correct way about it, but I was not sure how to explicitly provide a tuple type that's created by make_tuple,
let alone how to iterate on the values.

Any help with this would be greatly appreciated.

Thanks,
Barak
