Self is passed to dataclasses with no way to pass that reference in python code

[vladraduvidican]

This is the code I'm trying to run in Cython:

from dataclasses import dataclass

@dataclass()
class BookOrder:
    id: int
    time: int
    action: str
    value: float
    quantity: float

order = BookOrder(-1, -1, "-1", -1, -1)

def printme():
    print(str(order))

printme()

This is the error:

  File "main.pyx", line 11, in init main
    order = BookOrder(-1, -1, "-1", -1, -1)
ImportError: Building module main failed: ['TypeError: __init__() takes 1 positional argument but 6 were given\n']
