* check if the currently reached open-bracket (i.e. '{') * opens a: * - a definition type block (such as a class or namespace), * - a command block (such as a method block) * - a static array * this method takes for granted that the current character * is an opening bracket. * * @return the type of the opened block. */

 * @return    the type of the opened block.
