Man, you wrote the thing, it's not surprising it isn't a problem 
for you! :)

If `sc` is gone, and now there's some other classes you haven't 
heard of, that may be subclasses of scopes or contain various 
numbers of scopes, good luck guessing. `printf` isn't just for 
debugging, it's also for learning how the compiler is supposed to 
do things; that gets more difficult if you have to guess which 
member is the right one to pay attention to.

Idk, simplification is good, but maybe I'd just have chucked a 
global `alias printf = printfNoOp;` in or something.
