Hi,

I have class that takes an mpl sequence as its parameter like this:

X<mpl::vector<A, B, C> >

And I would like to be able to have the class be used without explicitly declaring the mpl sequence like this:

X<A, B, C>

I know this could be accomplished using variadic template parameters, but I am using an older compiler. I was wondering if there was a macro in boost to do this, such as:

template<BOOST_MPL_VARIADIC_PARAM_PACK(T)>

class X

{

typedef mpl::vector<BOOST_MPL_VARIADIC_PARAM_UNPACK(T)> type;

};

If a macro is not available, does anyone know how I could write a macro like this? Or what is the default type used for mpl sequences when a type is unspecified?

Thanks,

Paul
