In -**v2.2.0** however, you can decorate these methods with `\#@staticmethod` -and use "proper" Python syntax for calling them, **fig 1** revisited: - - \#@staticmethod - \#def copyright() - \#import time - © CheetahCorp, Inc. \$time.strftime('%Y', time.gmtime()) - \#end def -**Figure 1.1, util.tmpl** - -With the addition of the $staticmethod decorator, the `copyright()` -function can now be used without instantiating an instance of the `util` -template class.
