[Boost-users] tuple<...involves template par...>

Hi,

I have the following:

template<typename T>
class A: public std::unary_function<const boost::tuple<double,const
T&>&, void>{
public:
typedef typename std::unary_function<const boost::tuple<double,const
T&>&, void> parent_type;
typedef typename parent_type::argument_type argument_type;
void operator()(argument_type t)const{
   t.get<0>(); //error: expected primary-expression before ')' token
   t.get<1>(); //error: expected primary-expression before ')' token

};
};

Similar code without the template (i.e. fix say T = double) works
fine.

Anybody, pls help. Thanks.
