[R] Scope?

I find the following behaviour slightly disturbing:

> x = 6
> ex = function(x = x) x
> ex()
Error in ex() : recursive default argument reference

Can't  R  distinguish between formal and actual arguments? (Just kidding!)
Seriously, what bad things could happen if I was allowed to get the 
answer  6  here?
