I like the paragraph below, but the sentence above is repeated from
the earlier paragraph.

I understand they are confusing, hopefully it makes more sense with
the cone mode later.
* NONE == "No patterns at all"
* FULL == "all patterns allowed"
* CONE == "only cone patterns" (appears later)
Since this is just an internal detail, what if I switched it to
* MODE_NO_PATTERNS
* MODE_ALL_PATTERNS
* MODE_CONE_PATTERNS
Would that make more sense?
