C++ allows you to publish class-type template arguments
to class templates:
template<class T> struct X {
	typdef T the_type;
};

Will the C++ std allow a way to do this with non-type
template arguments?

The only two ways I can think of are:

template<int I> struct X {
	enum { the_int = I };
};
Drawback: can't do floats, let alone user-class types

template<int I> struct X {
	static const the_int = I;
};
Does this work?
Drawback: need to define the_int somewhere.
Will this work for an arbitrary user-defined class?
