It's not really a question of "able" to, or not.  I'm sure were Walter to  
decide to add this feature to D he would also be "able" to.

It also doesn't matter what another language choses to do.

Why you'd want an unused variable to be an error is beyond me - it has  
absolutely no effect on the resulting executable, if it did it would be a  
bug.

What matters, ultimately, from a user point of view is whether the feature  
exists or not.  We can solve that by having a 3rd party tool bundled with  
the compiler and this would be the best solution for all the reasons  
outlined earlier.
