Re: [SMARTY] Calling object methods

I have a fast fix for smarty to handle {$foo->bar()->display()}.
It is just fine to change the pattern matching in a few lines and it
works - I have tested it and use it it OZONE (www.ozoneframework.org -
but not released yet)

simpy change $this->_obj_start_regexp and $this->_obj_call_regexp in
Smarty_Compiler.class.php to
these given below:

$this->_obj_start_regexp = '(?:' . $this->_dvar_regexp . '(?:' .
     $this->_obj_ext_regexp . '(?:'.$this->_obj_params_regexp.')?'.
     ')+)';

$this->_obj_call_regexp = '(?:' . $this->_obj_start_regexp . '(?:' .
           $this->_dvar_math_regexp . '(?:' . $this->_num_const_regexp .
      '|' .     $this->_dvar_math_var_regexp . ')*)?)';

it works for me. no other changes were required as far as I remember.
