Complex numbers not implemented

[martin-henz]

5 + 0j 

should work according to the Python §1 specs, but gives:

ExpectedTokenError: SyntaxError at line 0 column 5
                   
5 + 0j 
     ^ Expected newline. Found 'j'.

Complex numbers should already be implemented, I think its a parser problem not a runtime problem.
