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.
