Yes, clearly you can do that, but it's obviously not your intent. All the docs use _ as the class name, and that's what you use internally. The class is named "_" and that's what people using it are going to expect to see if it becomes popular. You could make a better choice.
I think I'm getting the hang of HN ;)
But seriously, it seems like a pretty neat library. I just think your nomenclature is the suxxors and eventually we're going to look back on this trend and think, "boy, making everyone reading your code wonder which _ you're talking about is a pretty silly way to save a couple characters."

But you can call it whatever you want, so... who cares? The choice is yours... Being a pedant is hardly constructive.
