Comprehension inlining on Python 3.12.0rc1 breaks some tests

[Fatal1ty]

• mashumaro version: 3.9.1
• Python version: 3.12.0rc1
• Operating System: macOS 13.3.1

Description

Some tests are failed on Python 3.12.0rc1 and the root cause is the bug in comprehension inlining:

• https://github.com/python/cpython/issues/108654

What I Did

from dataclasses import dataclass
from mashumaro import DataClassDictMixin

@dataclass
class DataClass(DataClassDictMixin):
    x: dict[int, int] | list[float]

print(DataClass.from_dict({"x": {"1.1": "2.2"}}))  # will raise InvalidFieldValue

On Python <3.12 this code works as expected and prints: DataClass(x=[1.1]). To fix this issue we can use different names for keys and values inside comprehensions or wait for the bug fix in CPython itself before the final release.

This issue is fixed in python 3.12.0rc2
