Re: templated constanst

I just read the "limits" header (included with visual 2003),
and it uses the macro :

 #define _STCONS(ty, name, val) static const ty name = (ty)(val)

to declare numeric_limits member variables like has_infinity,
is_integer, etc, inside a struct declaration...

I wrote this simple code using such macro and the limits class
inheritance, and it does not compile...

#define MY_STCONS(ty, name, val) static const ty name = (ty)(val)

namespace mystd {

struct num_base
{
        MY_STCONS(bool, is_bounded, false);
        MY_STCONS(bool, is_exact, false);
};

template <class T>
struct num_procs : public num_base
{
   inline static foo() { return T(0); }
};

struct num_int_base : public num_base
{
        MY_STCONS(bool, is_bounded, false);
        MY_STCONS(bool, is_exact, false);
};

template <> struct num_procs<int> : public num_int_base
{
   typedef int T;
   inline static foo() { return T(20); }
};
