It would also turn on warnings.

I suppose I should also point out that you can just say

    module;
[download]

which would make your main program an anonymous module. I guess, for that matter, you could also say:

    class;
[download]

and get the same effect. I can just see instructors telling newbies to put that at the beginning of all their "class" assignments.

Hmm, if you want it even shorter, I bet

    role;
[download]

would even work. Hey, maybe any anonymous declarator should work. How 'bout:

    my;
[download]
