Assuming the attributes of object 'log' don't change at runtime (i.e.,
you're OK with early binding), I'd code:
def logit(fn):
method = getattr(log, fn.func_name)
def callit(**kwargs): return method(kwargs)
return callit
If you need to do late binding instead, you can move the getattr to
inside the body of callit.
