You might be interested in Michele Simionato's excellent decorator package.
The above could be written:
import decorator
def my_decorator(func):
return decorator.decorator(func, lambda: func(modulate(args)))
If your pattern is very common, you could even create your own
meta-decorator, like this:
def args_modulator(func, modulator):
return decorator.decorator(func, lambda: func(modulator(args)))
It's available on PyPi: http://pypi.python.org/pypi/decorator
In a nutshell, whatever part of your pattern is common, abstract out.
