Instead of child() vs concrete_child(), next_sibling() vs next_concrete_sibling(), etc, the default is switched: child() refers to the concrete syntax tree, and named_child() refers to the AST. Because the AST is abstract through exclusion of some nodes, the names are clearer if the qualifier goes on the AST operations
