+ *  get parsed while "unreasonable" ones cause a recursion error.
+ *
+ *  The compiler limits recursion now in key points which are guaranteed to
+ *  occur in any arbitrarily deep recursion: expression parsing, statement
+ *  parsing, and function body parsing.  A single recursion count is used,
+ *  so the actual limits for each expression (consisting of expressions,
+ *  statements, and inner functions) varies.
