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.
