Recursive Descent Parser for something simple?
For every other question with positive votes in the past, I've seen what I think are appropriate credits. This one shows 2 votes, but shows as line with "blank" for points in my reputation. Is there a significant time delay? (I haven't seen delays of more than a few minutes in the past). What don't I understand? (I'm assuming it isn't a bug, but I could only tag with "bug". Sorry.).
EDIT: Maybe I hit a daily reputation cap? (Hasn't happened before, so I don't know how to recognize it). If so, it isn't labelled very well.
