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. - Jonathan M Davis
