It is normal, whenever someone suggests changing the language, to 
talk about alternatives that don't involve changing the language. 
We can't properly discuss how important a change is without going 
through the existing ways to solve the problem.

If I proposed a change, or if Walter or Andrei did, we'd have the 
same sorts of discussion.

Do you think you should be exempt?
