New syntax allowed for the compiler

Hi, Here is a little patch to allow the compiler to recognize the following syntax : $foo->bar[$foo] $foo->bar[$foo]->bar $foo->bar[$bar]->foo->bar() $foo->bar[$foo]->foo[$bar]->bar() etc… These modifications recognize all the standard samples given in the file Smarty_Compiler.class.php… If anyone see a wrong recognized syntax… Renaud 57a58 > var $_arvar_regexp = null; 96c97,98 < $this->_dvar_regexp = '\$\w+(?:\[\$?[\w\.]+\])*(?:\.\$?\w+(?:\[\$?[\w\.]+\])*)*'; --- > $this->_arvar_regexp = '\w+(?:\[\$?[\w\.]+\])*(?:\.\$?\w+(?:\[\$?[\w\.]+\])*)*'; > $this->_dvar_regexp = '\$'.$this->_arvar_regexp; 132a135,136 > // $foo->bar[$foo] > // $foo->bar[$foo]->bar 139,140c143,146 < $this->_obj_start_regexp = '(?:' . $this->_dvar_regexp .
