</div>

these are invalid,

```auto
([x] := [1])

```

gives,

```auto
SyntaxError: cannot use assignment expressions with list

```

similarly,

```auto
([x, *_] := [1, 2])

```

also fails with the same error.

What could be the reasoning that they decide to not allow such a syntax?  
I do not see any problem with them.
