How to deprecate member function from outside?

[Dru]

Thanks for the reply
I will try to explain what I mean:

The first example shows that it is possible to deprecate a 
function separately from it's definition.

The second example tries the same for a member function but it 
fails with a compile error.


I want to know if it is possible to "fix" the second example?
