Creating dynamic objects with dynamic constructor args

[Greg]

I'd like to create objects on the fly from a pointer to the class 
using:  instance = klass()  But I need to be able to pass in variables 
to the __init__ method.  I can recover the arguments using the 
inspect.argspec, but how do I call __init__ with a list of arguments 
and have them unpacked to the argument list rather than passed as a 
single object?

ie. class T:
	def __init__(self, foo, bar):
		self.foo = foo
		self.bar = bar

argspec = inspect.argspec(T.__init__)
args = (1, 2)

??? how do you call T(args)?

Thanks.
