Cannot be declared variables

[GreasySlug]

Describe the bug?

I want to declare mutable variables using !, but panic occurs.

Reproducible code

>>> a = !1

Expected result

No error

Actual result

This does not reproduce in 0.6.0-beta.1.

Did you enter any other codes just before?

[GreasySlug]

Looking at the error code here, I think the error occurs in python 3.10.x version?

thread '<unnamed>' panicked at 'not yet implemented: unknown opcode: 166', compiler\erg_common\opcode310.rs:10:1

In fact, my python version is 3.10.8 and when I changed it to 3.11.0, the error did not occur.
