Solve the following python programming problem given the following code:
def critical_tryloop(f, identifier, detail) : 
    "Return the result of the supplied operation 'f', retry on exception.

    Will retry operation 'f' indefinitely until it does not raise, the delays
    used gradually increase so that whichever system is being tried is not
    overly stressed.

    :f: a callable that can be invoked like so 'f()'
    :identifier: a short string identifier for the calling line of code
    :detail: a string of the variables associated with the call, e.g. repo name
    :returns: the return value of operation 'f', if successful

    " 
    def on_tryloop_exception(e, delay) : 
        abdt_logging.on_retry_exception (identifier, detail, e, delay) 
delays = phlsys_tryloop.make_default_endless_retry () 
    return phlsys_tryloop.try_loop_delay (f, delays, onException = f) 

    
    

    Fix the buggy line: return phlsys_tryloop.try_loop_delay (f, delays, onException = f)

#Here is Python program to fix the buggy line: return phlsys_tryloop.
