- nodes can have special-cased hit ranges including "holes" (FunctionTypeLoc in void foo())
- token conflicts between siblings (int a,b;) are resolved in favor of left sibling
- parent/child overlap is handled statefully rather than explicitly by comparing parent/child ranges (this lets us share a mechanism with sibling conflicts)
