I think you're missing one level of wrapping.

>>> def a(x, y, z):
	print x, y, z

>>> def b(x, y, z='fruitbat'):
	print x, y, z

>>> x = []
>>> for func in a, b:
	def wrapper(func):
		def wrapped(*args, **kwds):
			print "wrapped!"
			func(*args, **kwds)
		return wrapped
	x.append(wrapper(func))
	
>>> x[0](1, 2, 3)
wrapped!
1 2 3
>>> x[1](1, 2)
wrapped!
1 2 fruitbat
>>>
