 1. `preprocess(ast: AST, options: object): AST`, if available, is called. It is passed the AST from the _parser_. The AST returned by `preprocess` will be used by Prettier. If `preprocess` is not defined, the AST returned from the _parser_ will be used.
 2. Comments are attached to the AST (see _Handling comments in a printer_ for details).
