The typed variant discriminator on the caixa-ast lexer surface — every Token’s carrying-shape (delimiter, reader-macro, atom, trivia) projects through this closed twenty-one-arm partition.

The gen_platform::IsVariant derive emits per-arm arm-discriminator predicates — Self::is_l_paren, Self::is_r_paren, Self::is_l_brace, Self::is_r_brace, Self::is_l_bracket, Self::is_r_bracket, Self::is_quote, Self::is_quasiquote, Self::is_unquote, Self::is_unquote_splice, Self::is_str, Self::is_int, Self::is_float, Self::is_bool, Self::is_nil, Self::is_symbol, Self::is_keyword, Self::is_shebang, Self::is_line_comment, Self::is_newlines, Self::is_whitespace — so every downstream consumer that only needs the arm-discriminator projection (not the borrowed field value) reaches for one typed dispatch on the substrate primitive rather than a hand-rolled matches!(k, TokenKind::X | TokenKind::Y(_)) literal. Peer of the sibling crate::NodeKind / crate::trivia::TriviaKind IsVariant lifts already on the caixa-ast surface (7f6aa98 / 44873ae) — extends the same discipline onto the token-family axis every downstream lexer / parser / authoring consumer partitions on (the internal tokenize test-harness trivia filter today, a future caixa-lint no-tab-indentation or no-map-in-defcaixa-slot rule that walks tokens before parsing).
