I noticed this change when merging with the latest master. What does
`DYNAMIC_STAR` mean? The original `WILDCARD` name was more theoretical. How is
`DYNAMIC_STAR` different from `STAR` (other than being `**`)?
Can we call it `WILDCARD` and `isWildcard()` that the string is `**`,
presumably for internal reasons, seems less worth calling out in the name.---
