I also find writing decorators a bit

Particularly for the pattern
@deco(arg1, arg2) def fn(arg3, arg4):

Perhaps doing something with partial might help here. Anyone here interested
in exploring this?
I can't think of a way that partial would help. But would
you find it easier if you could do something like this?
class deco(Decorator):
def __init__(self, arg1, arg2):
self.arg1 = arg1
self.arg2 = arg2
def invoke(self, func, arg3, arg4):
# function body
Implementation:
class Decorator:
def __call__(self, func):
self._wrapped_function = func
return self._wrapper
def _wrapper(self, *args, **kwds):
return self.invoke(self._wrapped_function, *args, **kwds)
