I've thought about this some more, and my conclusion is: 
irrelevant.

At the end of the say, when the code is compiling, it can be in 
only one of two states:
* deprecated methods are illegal
* deprecated methods are legal (with or without warnings: who 
cares)

So basically, without worrying about how the "-d" switch works 
(or will work in the future), we can have a version(deprecated) 
that returns true if "using deprecated stuff is legal" and false 
otherwise.

Basically, I think having a version(deprecated) and a "warn when 
using deprecated stuff" are two orthogonal concepts that can 
coexist without clashing.
