Solve the following python programming problem given the following code:
def __call__(self, function = None, hookwrapper = False, optionalhook = False, tryfirst = False, trylast = False) : 
    ' if passed a function, directly sets attributes on the function
        which will make it discoverable to register().  If passed no function,
        returns a decorator which can be applied to a function later using
        the attributes supplied.

        If optionalhook is True a missing matching hook specification will not result
        in an error (by default it is an error if no matching spec is found).

        If tryfirst is True this hook implementation will run as early as possible
        in the chain of N hook implementations for a specfication.

        If trylast is True this hook implementation will run as late as possible
        in the chain of N hook implementations.

        If hookwrapper is True the hook implementations needs to execute exactly
        one "yield".  The code before the yield is run early before any non-hookwrapper
        function is run.  The code after the yield is run after all non-hookwrapper
        function have run.  The yield receives an ``_CallOutcome`` object representing
        the exception or result outcome of the inner calls (including other hookwrapper
        calls).

        ' 
    def setattr_hookimpl_opts(func) : 
        setattr (func, (self.project_name + '_impl'), dict (hookwrapper = hookwrapper, optionalhook = optionalhook, tryfirst = tryfirst, trylast = trylast)) 
        return func 
if (function is None) : 
        return <MASK> 
else : 
        return setattr_hookimpl_opts (function) 
    
    Given the code above, what is a proper replacement for <MASK>? Choose among: optionalhook, hookwrapper, setattr_hookimpl_opts, function, tryfirst, trylast, self
assistant
#Here is a proper replacement for <MASK>.
