Expand description
Lexer and token/trivia types for Daml source text. DAML lexer: source text → tokens with spans.
First stage of the real parser pipeline (lexer → layout → parse). Comments
(line --, nested block {- -}) and string/char literals are resolved
here, so no later stage can ever mistake -- exercise the option for a
ledger action.
