-- Function: treesit-node-type node
     Named nodes have “types” (*note node type: tree-sitter node type.).
     For example, a named node can be a ‘string_literal’ node, where
     ‘string_literal’ is its type.  The type of an anonymous node is
     just the text that the node represents; e.g., the type of a ‘,’
     node 480is just ‘,’.

The “480” I assume is not suppose to be there.  This is the emacs-29 branch updated today (Dec. 29).
