Comments
Comments start anywhere outside a string with a double hyphen (--). If the text immediately after a
double hyphen (--) is anything other than double left brackets ([[), the comment is a short comment,
which continues only until the end of the line. If double left brackets ([[) follow the double hyphen (--),
it is a long comment, which continues until the corresponding double right brackets (]]) close the
comment. Long comments may continue for several lines and may contain nested [[ . . . ]] pairs.
The table below shows how to use code comments.
