I'm not sure the `_` is appropriate, as it's not really a 'hidden' thing per se... I dunno. Aesthetically, underscored things look ugly to me, so I try to use them only when it's important to hide that part of the implementation (because there's a property for modifying it, or having it exposed makes the class too confusing). This is a pretty straightforward thing, so it doesn't seem like it's worth uglifying it, but yeah, it's an aesthetic thing so its hard to debate either way. I could see getting rid of the all caps and going with just `timer` or something...
