I really like curly, latedef, shadow, and trailing. The first three have actually saved me from myself a few times. Mind adding them back?

- Curly requires `{ }`'s on if statements, even if they're only one line long.
- Latedef forces you to define variables before you use them, so hoisting doesn't bite you.
- Shadow warns when you clobber another variable's name.
- Trailing forces you to keep trailing whitespace out of files.
