The pypy implementation of the complex builtin may give you some
clues.
I found it helpful.

thank you
I will have to take a closer look on __new__

what do you think of this design?

Hello
I am trying to customize the handling of complex numbers
what I am missing is a builtin possibility to create
complex numbers in polar coordinates
so first I wrote a standalone function
>>> def polar(r,arg):
... re, im = r*cos(arg), r*sin(arg)
... return re + im*1j
then I tried t
