[Discuss-gnuradio] Python pass parameter as const *gr_complex?

Hi list,
 
I am trying to use the gr::digital::constellation::decision_maker(.) method from python, but I get an error message.
In order to reproduce call in python:
 
import gnuradio.digital
a = gnuradio.digital.constellation_qpsk()
b = complex(1+1j)
a.decision_maker(b)
=> TypeError [..] argument 2 of type ‘gr_complex const*’
The C++-implementation is wrapped by SWIG, where the error occurs.
 
This might be a silly question, but what am I doing wrong?
 
Thanks for any help.
 
Best regards
 
Stephan Ludwig
