This is a little misleading.

Well, it's the worst case runtime. In the normal case it's not that bad, but the fact remains that in general lexing is more efficient than parsing.

You're right that most grammars can be parsed in linear time (actually many grammars have their current shape to facilitate parsing).

[holli]: did you soak the controller boardlet?
[Eily]: could be worse, you might have ruined your tea with the content of the keyboard
[holli]: if you didnt you should be fine
