python pysemcom.py --help raises Syntax Error

[lucas0]

File "pysemcom.py", line 12
    class PyComplex(metaclass = ABCMeta):
                              ^
SyntaxError: invalid syntax

when trying with python3

it doesn't even pass line 7:

Traceback (most recent call last):
  File "pysemcom.py", line 7, in <module>
    from subprograms.loader import SubProgramLoader
  File "/home/lucas/Lux/res/complexity/subprograms/loader.py", line 5, in <module>
    from typing import ClassVar
ImportError: cannot import name 'ClassVar'

Can you fix this?
