Some decorators should only be used in the outermost layer.
A decorator that augments the original function and add a configure parameter is one example.
from functools import wraps
def special_case(f):
@wraps(f)
def _(a, b, config_x=False):
if config_x:
print "Special case here"
return
return f(a, b)
How can I avoid decorators like this getting decorated by another decorator?
EDIT
It is really disgusting to let everyone trying to apply a new decorator worry about the application order.
So, is it possible to avoid this kind of situation? Is it possible to add a config option without introducing a new parameter?
