There was a problem hiding this comment.
Since I had the same big if statement show up in my parser -- would it be helpful to document what order to micro-optimize the branches in somewhere based on frequency of what appears in the wild (e.g. I assume app belongs way higher).
(Obviously not highly relevant to this PR itself).
