      Description

      I wanted to use COALESCE in DQL with a function (e.g. CURRENT_TIMESTAMP()). If I run this DQL, I receive a syntax error exception like this one:

      montbook:marlow mprebio$ php scripts/doctrine.php orm:run-dql "select COALESCE(CURRENT_TIMESTAMP()) from Project\Entity\User user"

      [Doctrine\ORM\Query\QueryException]
      [Syntax Error] line 0, col 33: Error: Expected Doctrine\ORM\Query\Lexer::T_CLOSE_PARENTHESIS, got '('

      I've traced this error to Doctrine\ORM\Parser::ScalarExpression() which tries to interpret the current_timestamp function as a SimpleArithmeticExpression or as a StateFieldPathExpression (first if). As far as I understand this part of the parser, the function call should lead to the if part with $this->_isFunction(). Therefore I added a "and !$this->_isFunction()" to the first if clause. After this change everything works as expected: The above query returns the current timestamp (many times because of the from since DQL needs a from part).

      Reordering the ifs should work too.
