 When highlighting a file, Tree-sitter will keep track of the set of scopes that contains any given position, and the set of definitions within each scope. When processing a syntax node that is captured as a `local.reference`, Tree-sitter will try to find a definition for a name that matches the node's text. If it finds a match, Tree-sitter will ensure that the *reference* and the *definition* are colored the same.

 Then, we'll set up a local variable query to keep track of the variables and scopes. Here, we're indicating that methods and blocks create local *scopes*, parameters and assignments create *definitions*, and other identifiers should be considered *references*:
