It's so weird.
I just run cargo fmt and CI fails
Restore it and CI is successful again

Before this PR the Ubuntu CI also has a probability faild:https://github.com/erg-lang/erg/actions/runs/3984374464/jobs/6830520255

Local tests passed, but CI failed @mtshiba

This is not a mistake, but a request for improvement. If a class has a decorator, it is supposed to accept subsequent method definitions. I would like this to be the case even when decorators are not attached.

P.S.

>>> @id
... f x = x
...

The behavior seems to be that if a decorator is attached, the methods' definition is expected, but this behavior is not strictly correct, since non-classes can also have decorators. It would be necessary to determine the class definition. It would be difficult to implement in earnest, but as a simple implementation, if a Class is placed immediately after the =, it can be judged as a class definition.

I have found a problem that if you type anything other than English in the repl, there will be a lot of problems (I will solve this problem).

[mtshiba]

Decorators not working properly.
