toStrictEqual meets error when used in such situation

[yjhmelody]

I define a Option:

export class Option<T> {
    @inline
    constructor(
        protected readonly _val: Box<T> | null = null,
        protected _isNone: bool = true
    ) {}


    @inline
    static Some<T>(val: T): Option<T> {
        return new Option<T>(Box.from(val), false);
    }

    @inline
    static None<T>(): Option<T> {
        return new Option<T>(null, true);
    }

    @inline
    @operator("==")
    eq(other: Option<T>): bool {
        return this._val == other._val;
    }

    @inline
    @operator("!=")
    notEq(other: Option<T>): bool {
        return !this.eq(other);
    }

   // ...

And the Box:

export class Box<T> {
    constructor(protected readonly val: T) {}

    /**
     * Create a Box version of value
     * @param val boxed value
     * @returns value of Box version
     */
    @inline
    static from<T>(val: T): Box<T> {
        return new Box(val);
    }

    @inline
    @operator("==")
    eq(other: this | null): bool {
        if (other === null) return false;
        return this.val == other.val;
    }

    @inline
    @operator("!=")
    notEq(other: this | null): bool {
        if (other === null) return false;
        return this.val != other.val;
    }
   // ...
}

But I cannot do toStrictEqual for option.

I will definitely take a look into this soon. Thanks for the report.
