Hi,
the value 'pos' attribute as per phpdoc (sqlparser.lib.php, Line 65) is:
@param int $pos Position of an element
So, it should be the index of first character of the element but from [0] it looks like it is set to index of the last character of element + 1. Also, for quote_backtick types and few others the value of pos is 0.
What should be the appropriate value for pos?
1. position of initial character of the element. (I personally prefer this one).
2. position of last character of the element.
3. position of last character of the element + 1.
Is it used somewhere yet??, because changing its behaviour can cause side effects.
