Oh, I also should have mentioned that there's some explanation at:
http://www.python.org/peps/pep-0318.html
Specifically on parameterizing:
"""The current syntax also allows decorator declarations to call a
function that returns a decorator:
@decomaker(argA, argB, ...)
def func(arg1, arg2, ...):
pass
This is equivalent to:
func = decomaker(argA, argB, ...)(func)
The rationale for having a function that returns a decorator is that the
part after the @ sign can be considered to be an expression (though
syntactically restricted to just a function), and whatever that
expression returns is called. See declaration arguments [15]."""
But playing around with it is, IMHO, definitely the best way to figure
it out. =)
