``` ruby v = 1; [[2]].each{ |(v)| }; p v _ = 1; [[2]].each{ |(_)| }; p _ ``` prints ``` 1 2 ``` You can see here that `v` is still `1` but `_` isn't shadowed properly and is being assigned `2`. Reproducible from 2.3.8 to 3.0.2 ...Nakilon (Victor Maslov)
Bidirectional assignments should be implemented to make swapping values: ``` var1, var2 = var2, var1 ``` much shorter: ``` var1 vv^^ var2 ```Nakilon (Victor Maslov)
