Are these parameterless static methods
or should this be self._handlerClass.thisIsTheMethodName(self)
or does self get auto-bound even though not a _handlerClass instance?
(I have never needed or done such delegation.)

My immediate thought would be to start with
_forwarded = set(......) # of forwarded method names
def __getattr__(self, name):
if name in _forwarded: return getattr(self._handlerClass, name)
but I am not sure if this gives the right wrapping and binding.
