version(deprecated)?

[monarch_dodra]

I'm wondering if there is a way to know you are in deprecated 
mode or not?

The deprecated attribute is great, because it gives a clear 
compile error (as opposed to a static if, which just hides the 
function completely).

But the attribute alone is not enough: I have a class with a 
deprecated method, which consumes a book-keeping attribute: Not 
only will this attribute exist even though it has become useless, 
but the other functions will keep updating this attribute, even 
though it has no more consumers.

What's more, I'd still want to unittest that function, but 
obviously, only when compiled in "-unittest -d".

So I have a problem.

--------
Finding out if the compilation mode is deprecated is easy enough:

//----
deprecated @property void deprecateExists(){}
enum deprecatedActive = is(typeof(deprecateExists));
//----

The thing is it's kind of dirty, and I wouldn't want to have to 
copy paste this in all of my modules, just to know whether or not 
deprecation is active...


--------
We've currently implemented "version(assert)" and 
"version(debug)". Do you think we should request having a 
"version(deprecated)"? I think it would be very helpful. Thoughts?
