Hello Luiz Henrique,

you are right with block() , I am sorry.

I get this in Lua 5.1:

Lua 5.1.4  Copyright (C) 1994-2008, PUC-Rio

Left block

I noticed that the Lua 5.1 parser seems to call the body() procedure
multiple times when parsing statements that are part of a Lua body, for
example statements in a `then`, `else` or `do` body.
body()  is for parsing function bodies:
   /* body ->  `(' parlist `)' chunk END */

Perhaps you mean block():
   /* block -> chunk */
