Interestingly, two days ago I've imagined the same solution, except I was using
`.=` instead of `mixin`. The `.=` syntax is reminiscent to assignment operators
like `+=` (but, of course, it's not an operator, since its right hand side is
not a standalone expression). Reusing your examples:
```javascript
export const someMixin = obj => obj .= {
method1() {return super.method1()},
Method2() {...},
data: 42
};
```
and, for classes (but with mandatory `class`-keyword):
```javascript
C .= class {
m2() {super.m2()}
}
```
