D will stop you from shooting yourself in the foot if it can do so in a way 
that doesn't actually limit you, and it does do quite a few things to make it 
harder to shoot yourself in the foot, but it certainly doesn't ultimately stop 
you from doing so. However, if it _never_ makes sense to declare a variable 
beginning with two underscores, I don't know why the compiler wouldn't forbid 
it other than the fact that it probably inserts such variables prior to when 
it would do the semantic analysis to check whether variables started with 
underscores, in which case, catching the user's variables that start with two 
underscores while permitting the compiler's variables could get tricky.
