Hi All

This doesn't work.

template<typename T> struct S
{
    typename disable_if<is_const<T>, int>::type mutating_method();
};

I understand why not, although only after the compiler threw it out, but
obviously (in hindsight),
the method itself is not a template, so can't be selectively instantiated.

The question is whether and how I can achieve the effect I'm after, ie.,
that the method
is not present if the struct is instantiated with a const type?

Thx, Rob.
