--- A facade for tokenizing input text and parsing it into an AST.
--- @param input string The input text to parse.
--- @param tokens { [integer]: string, [string]: true | fun(self): string } The tokens to use for parsing.
--- @param topLevel Parsable The top-level parser to use. This should ideally consume the entire input, including the ending eof token.
