Python 3.10 match case fails with '|'

• Nuitka version, full Python version, flavor, OS, etc. as output by this command (it does more than you think, and we are adding more all the time):

  python -m nuitka --version 0.7.6 Commercial: None Python: 3.10.2 (main, Mar 5 2022, 23:17:41) [GCC 8.3.0] Flavor: Unknown Executable: /home/david/Dev/python/dev_venv3.10.2/bin/python OS: Linux Arch: x86_64 Distribution: Debian 11

• How did you install Nuitka and Python

• Via Pycharm settings

  Did you use pip, anaconda, deb, rpm, from source, git clone, then install into a virtualenv or not, this is very important usually. No

• The specific PyPI names and versions

  It should be taken from this output if there specific packages involved, e.g. numpy, you are expected to shorten this to the relevant ones.

• Many times when you get an error from Nuitka, your setup may be special

  Then even a print("hello world") program will not work, please try that and report that instead.

That works!

• Also supply a Short, Self Contained, Correct, Example

from enum import Enum


class strEnum(str, Enum):
    def __repr__(self):
        return str(self.value)

    def __str__(self):
        return str(self.value)

    @classmethod
    def list(cls) -> list[str]:

        str_list: list[str] = []

        for x in cls:
            str_list.append(x.value)

        return str_list


class DATATYPE(strEnum):
    BLOB = "BLOB"
    BOOL = "BOOL"
    CHAR = "CHAR"
    CURRENCY = "CURRENCY"
    FLOAT = "FLOAT"
    INTEGER = "INTEGER"
    REAL = "REAL"
    TEXT = "TEXT"



test_str = DATATYPE.BLOB

match test_str:
    case DATATYPE.BLOB | DATATYPE.TEXT :
        print(f"DBG {test_str=}")
    case _:
        print(f"DBG Not Blob")
